this grinder is better than most admit, get it when its on sale though
For some context, I like to brew coffee in multiple ways (espresso, pour-over, french press, etc) and do not want multiple grinders. I also did not want to pay anything more than about $250 for a grinder from a reputable brand. Prior to the Fellow I had a standard Baratza Encore (non-ESP) which was basically impossible to get a good grind for espresso on. Other issues I had with the baratza were its chute where grinds would come out, it would just constantly get clogged and oily which made it quite a high maintenance device. So now we arrive at the Fellow Opus. I had a hard time deciding between this and the Baratza Encore ESP, and now Baratza offers the ESP Pro which is a good competitor. I tried an ESP for a week, but the main thing that made me switch from Baratza was that the ESP uses the same chute design as the non-ESP and I hated how clogged and blocky my espresso came out on both machines. Pros: -The anti-static tech works wonders for me. With my Baratza, I would have to do a lot of WDT puck prep because all the espresso came out in blocks. I have had virtually 0 clumps in my espresso grinds on this machine. (pro-tip, you should still clean the contact points every few weeks to keep the anti-static tech working as intended) -Its pretty quiet for a grinder which I was actually really happy about since the Baratza is like a banshee in the morning by comparison. -The hopper cover is a great large dose cup for my drip coffee grinds, and it doubles as a bellows decently enough. -The grind cup and the espresso grinds insert are great, I never have a mess after grinding except for a few sprinkles. I have yet to come across any grinder at this price range that doesn't make at least a bit of a mess after grinding. -The Beanie App is your best friend for adjusting grind sizes using the inner ring! Micro-adjustments with the inner ring are not that hard, many reviews blast this mechanism WAAAAAY to much for the price of this machine. Yes, its not the most intuitive system, but its a single dose hopper. Once you realize your grind is too coarse/fine, its already empty and is easy to take off to adjust. Using Beanie and the same beans makes this easier because it means less adjusting once you find your grind size. -SOOOOO easy to clean, the baratza by comparison was a huge PITA to clean and it would just gather grinds in every darn corner of the chute. -Looks pretty nice for a grinder at this price point. Yes, its plastic and not metal, its an entry-level grinder.... -I find the grind timer button intuitive and simple. I like to do other coffee prep tasks while my stuff grinds, so having everything on a timer is nice. I never have to manually shut off the grinder. Recommend one press for espresso and two for pour-over/french press Cons: -The bottom plate where the dosing cup does scratch easily. I don't think its a huge deal as it mostly gathers really small scratches and even so, it wouldn't be hard to put some felt down if I cared more. Keep it clean of excess grounds and you'll be fine. -The hopper does sometimes catch a few beans. This happened in my Baratza as well, so no big deal to just run the grinder again for 5s to get the last few bits. -Inner adjustment ring is still not the most intuitive design, its NOT nearly as bad as I see so many reviews say for the reasons I put in my Pros section. (Use the Beanie app, it helps so much) -I have to knock the hopper 2-3 times with my hand to get any sticky grounds out. Not a big deal since I have had to do this with my Baratza even more cause of its chute design. Summary: I really love this grinder and think its a perfect entry-level grinder that can basically grind anything decently. Its a jack of all trades, master of none in particular. Especially when its on sale for around $150, I don't think there's as good a versatile grinder with this fine of an adjustment system on the market, including Baratza for all of its clogging issues.

Took Some Experimenting But Very Satisfied
I had a basic Krups grinder for several years. It was loud and messy with lots of static in the grounds bin and it would jam frequently with harder beans. So after some research I selected the Fellow Opus Conical Burr grinder. It took some experimenting but I eventually found that a courser setting (10) worked best for my Cuisinart Pure Precision Pour Over Coffee Brewer on the bold setting. I have also discovered that I need less beans (scant 1/2 cup vs 2/3 cup) which will save some money over time. It took some experimenting with settings because my initial tries yielded coffee that was too strong and bitter, but now I am very happy so far. The Fellow Opus grinder is definitely quieter and consistent and there is almost no static in the grounds bin. It is fast and easy to use and compact - looks good on the counter. I would love to buy the Fellow Aiden Precision coffee maker once my current brewer stops working. These products are pricey but so far I am very satisfied with my grinder upgrade.

High Maintenance & getting worse
UPDATE: *** Dropping this to a 1 star. The amount of coffee retention is about 25% per grind after 6 months. I also find myself completely cleaning the whole grinder every single grind. I mean, who wants to completely tear down your grinder every day. Not to mention the mess. There are coffee grinds ALL OVER MY ENTIRE COUNTER each morning. I spend more time cleaning this grinder every pull then I do a shot then my entire morning routine. I give up on this grinder. I have tried week after week, watched hours of YouTube vids...Its crazy. This is by far the single MOST HIGH maintenance appliance I have in my entire house...or have had in like the last 10 years. How did this get signed off by QC within the FELLOW company? Forget everything below, just save yourself time and $$ and go get something else. Don't become another victim of overhyped marketing and under performance. Did my research and thought this was going to be a good choice. I liked the look and multiple reviews from Amazon & YouTube. At first, meaning the first 2 months, the grinder worked great...no complaints, as the grinder ran flawless. It could grind coffee to various coarse ground sizes, NP. But after 2 months I started to notice more and more coffee grind retention in the grinder itself. I would regularly clean like 1x week. My usage was one double espresso a day. So on average, 7 double's a week, again with a weekly cleaning. But after a few months the grind retention would be more and more frequent. Like other reviews, it seemed like every 2 or 3 days, I would have to do a full cleaning just to minimize the retention inside the grinder. I also used a scale and would measure coffee in vs. coffee out. I was losing approx. 2~3 grams per 17~18 gram grind for a double. This is frustrating since I measure my coffee weight to target 17~18 grams depending on my pull. Now, I have to "guess" how much coffee grind retention is going to be trapped in the grinder. I find myself grinding several times to meet the desired weight. It's a guessing game. But to be fair, I dial in my grinder to adjust my pour, I am not sure the average coffee person would care as much. But then again, for this price, I would expect more. The second issue is the anti-static mechanism has seemed to fail. Meaning, now when the coffee grinds come out of the grinder into the small cup at the bottom of the grinder, I have coffee grinds flying everywhere, in and out of the cup. It's like fine dust being blown down into the cup, and flies out onto the surrounding countertop. I have had the grinder now for 7 months with this happening at about month 5 or 6. I can deal with this, as it's more of an annoyance, but that's one of the features I paid for in this grinder. Now I have to wipe down the counter in about a 2 foot radius from the grinder each time of use, due to the fine "mist" of coffee grinds. My last complaint is the conical burr grinder itself inside. Due to the high coffee retention in the grinder, I have to clean out the grinder now every few grinds. Which means I have to remove the conical burr grinder inside. Not that big of a deal but the last few times, the locking mechanism has stuck to the lock position and I could not manually remove the burr grinder. It has a hand twist removal system, but I have to use pliers to twist this off since it was physically stuck. I have already bent the metal latch which your fingers would clasp around to twist using the pliers. I am very concerned that any day the metal latch is going to break, and my burr grinder will be stuck forever inside. Not really sure how to remove it once that happens. If this breaks, I'll go from 2 stars to 1. Overall this grinder seems like a great idea on paper, sleek and modern. I purchased the white color to match my other appliances. Looks good, but functions "iffy". It's high maintenance cleaning with every 2 or 3 grinds due to the coffee retention build up inside the grinder. Even with hitting the sides, shaking the thing, or using the top down "bellow" as I grind, this seems to help a bit, but still lot's of retention. Many people have complained about the coffee retention, some machines seem to do this more than others. The anti-static feature is now non-existent, and my biggest new concern is the conical burr grinder itself is getting more and more difficult to remove to clean. I guess I got unlucky. Would love to try another Fellow Opus Conical Burr Grinder to see if the one I have is a lemon, but I'm not going to gamble another $200 to test that theory.

Consistent grind & still producing a great cup 2 years later with minimal upkeep
We've been using this for almost a couple years now with daily pour-over in our Hario v60 using Cafec filters as we don't have an espresso machine yet. The grind has been quick and consistently sized, doing roughly 25g for our two servings in less than 30 seconds. You can get really granular with the grind size, however we finally landed at a sweet spot for the Hario around 9.5. Since we don't usually bother spraying down the beans which would probably help, there is a lot of static resulting in grounds sticking to several sections. It's never caused any kind of clog though, just a small mess to clean up. The included cup is handy to use for weighing and adding, though at this point we use a Muvna scale with a pour spout instead as it's quicker and more aesthetic, haha. Overall been a great, reliable machine that's easy to use, it processes all the beans added, and you can still hold a conversation while it's running. Hopefully it'll continue to last, but I would absolutely consider Fellow again for a grinder.

Massive retention, messy workflow, cheap-feeling plastic
This grinder looks fantastic at first glance. Very clean, very elegant, and it honestly looks way more expensive than it is. The magnetic dosing cup is genuinely great — I didn’t even know that was a thing until I used it, and it’s probably my favorite part of the whole grinder. Unfortunately, the experience goes downhill pretty quickly once you actually start using it. Retention is the biggest problem The retention on this thing is wild. After using it maybe 5–6 times, I ran it empty, tapped it a bunch, and did a dry run — and almost half a dose came out afterward. That’s not “a little retention,” that’s enough to completely mess with single dosing. You basically need a scale under the dosing cup every time because what comes out is nowhere near what went in. Mess everywhere The grinder has a habit of dumping fine grounds out when you accidentally bump it, which is annoying on its own — but it always seems to happen right when the dosing cup is out, because that’s when you’re putting it back. Those fine grounds end up exactly where the cup sits, so when you put it back in, you’re grinding dust into the surface. Which leads to the next issue… It looks premium but feels cheap The plastic feels like the kind that scratches if you look at it wrong. I only ever wiped it down with clean, super soft microfiber towels, and the only “dirt” on it was coffee dust from the grinder itself — and it still scratched everything from the outside of the grinder to the dosing cup and where it sits. Same story up top. After one grind, the hopper area already has a ton of fine coffee dust. Enough that the really neat gravity-sliding lid won’t go down properly unless you clean it first. And cleaning it just adds more chances to scratch everything. It’ll close if you push it down obviously but that smooth gliding close it has when it’s clean just won’t happen which is a shame because it looks so cool when it does that. Dosing cup: great idea, awkward in practice I love that the dosing cup lip fits a 54mm portafilter perfectly — that part is actually really well thought out. But in practice it creates a huge mound of coffee in the basket. The moment you try to WDT or even touch it with a distributor, grounds spill everywhere. Shaking and tapping the cup upside down doesn’t do anything other than transfer it to the portafilter. Honestly, a dosing funnel would’ve made more sense here, but I appreciate the intent. Grind quality (espresso only) I only used this for espresso. The grind seems reasonably consistent at first, but there are random chunks mixed in, and combined with the retention, shots can be inconsistent. Some slightly under-extracted, some slightly over-extracted — nothing terrible, but nothing impressive either. The coffee isn’t bad, but it mostly just tastes like… coffee. You can barely pull subtle notes out of it. Occasionally it’ll produce a sweeter shot, but it feels random rather than repeatable. Final thoughts There are some genuinely good ideas here — especially the dosing cup and the overall design — but the retention, mess, cheap-feeling materials, and inconsistent workflow completely overshadow them. It works, but it’s frustrating to live with. 2 stars because it nice to look at, but too many real-world issues to recommend for espresso-focused use

Works well, looks good, but...
I like the Fellow design style. It's simple, and unobtrusive. I use the grinder for pour-over, AeroPress, and Moka Pot coffee making. Adjusting the grinder to the suggested appropriate settings works out well. Whether or not the Opus really gives a usable espresso grind is left for others to comment on. That's the good news. The receiver cup's somewhat problematic. Fellow's Ode grinder uses a strong magnet to hold the cup in place. For some reason, the Opus uses a weaker magnet than can be easily overcome, meaning the discharge from the grinder may or may not all go into the cup. Maybe this is nit-picking, but why Fellow used a magnet that doesn't firmly hold the cup place escapes me. While the Ode cup has baffles, to direct pouring the ground coffee, that upset at least one YT reviewer, the Opus cup uses flats in the interior to direct pouring. That works - mostly, A ring is fitted to the top of the cup, although I'm not sure I get why it's used. Does Fellow expect ground coffee to billow out of the cup? Beats me. Anyway, the ring has to come off to pour out the ground coffee. Over time, debris from beans builds up both on the actual burrs, and on the sloped floor of the grinder hopper. Someone came up with a silicon bellows that's supposed to blow the debris through the grinder. Don't bother, it doesn't happen. Because the grinder and receiver cup are plastic, "static cling" is the big culprit here. Plan on misting beans with the least bit of water to manage this problem. Keep in mind "more is >not< better". Because of the plastic construction, and the need to take the hopper off for effective cleaning, I'm not sure how this will impact the grinder's service life. The same is true for the adjustment for grind size. There are definite clicks while adjusting the fineness. Again the question of wear and longevity comes to mind. The grinder has only one power control, a push button on the base of the grinder. Push it once, and the motor runs for 30 seconds, which should be more than enough for small batches (i.e., 1-3 cups). Run time can be increased with multiple button presses. The motor can be stopped by pushing the button while the motor's running. At least one YT review objected to the Ode grinder's beeping. It's easy enough to figure out when all the beans in a batch are ground; the motor speeds up noticeably. The same's true for the Opus - and it doesn't beep to announce the obvious. Or does it? For some reason, when the Opus is plugged in, it beeps once. So far, I haven't heard any beeps before, during, or after grinding. But any time I plug the Opus back in, it beeps. Huh? In the main, I'm pleased with the Opus. It's adjustable to different grinds, it works without significant annoyances, and I suspect it'll last for quite a while. It's the niggling details, such as the weak magnet, and the problems with clearing out debris that keep the Opus from a fifth star. A caveat about browsing on the Fellow website. If you look at a particular item on the website. expect to get at least a few IMHO nagging emails about "are you ready to buy [whatever]".

Best Coffee grinder ..!!
I honestly debated buying the Fellow Opus for weeks, but I finally pulled the trigger, and I'm genuinely obsessed. For years, I struggled with trying to make one grinder do everything—it was always a messy compromise between my morning espresso ritual and the big French Press batch I make on weekends. The Opus has completely solved that problem. The 41 grind settings are the absolute hero here. I can now effortlessly jump from a super-fine, consistent grind for my espresso machine (seriously, the consistency is top-notch, leading to perfect pulls) to a perfectly uniform, coarse grind for my French Press or Cold Brew. The clean taste and absence of "fines" in my brews is a night and day difference. I'm finally tasting the nuanced notes in my beans that I was missing before. Beyond its performance as a true workhorse, this thing is a beauty. The Matte Black design is sleek, compact, and looks incredibly sharp sitting on my counter—it instantly elevated the look of my whole coffee bar. It's quiet enough not to wake up the whole house, and the dose cup system makes my morning routine so much cleaner. If you're a home brewer who demands quality across all brew methods, trust me, this is the one. It's the best coffee upgrade I've made all year.

Perfect grinder for quiet mornings and delicious cofee
I’ve been using the Fellow Opus for a few weeks now, after getting the Aiden, and the two pair perfectly. Adding the Fellow Drops to the mix — where they give you exact grind settings for the Opus and brew settings for the Aiden with each bag — has made my coffee experience so much smoother. With all the different settings on the Opus, it's easy to get the cup of coffee you want whether it's espresso, french press, cold brew, or pour over. It’s also pretty quiet, which makes for a much more calming morning experience than before, especially because I wake up a lot earlier than my husband. The matte black looks beautiful and fits easily on our small counter, and feels solidly made. Adjusting the grind is simple, the magnetic catch cup keeps mess contained, and cleanup takes seconds. If you want consistently great coffee without noise or fuss, the Opus is totally worth it. Really glad I added it to our setup!

Un moulin à café élégant et performant
Le moulin à café Fellow Opus est vraiment impressionnant. Son design moderne et épuré se marie parfaitement avec n'importe quelle cuisine, et il est incroyablement facile à utiliser. Les différents réglages de mouture permettent d'obtenir la granulométrie parfaite, que ce soit pour un espresso serré ou un café filtre léger. Le mécanisme est précis et le broyage est homogène, ce qui améliore vraiment le goût du café. De plus, il est robuste et durable, ce qui en fait un excellent investissement pour tout amateur de café. Je suis ravi de cet achat !

Excelente molino por el precio. Muy bueno para empezar adicional el diseño y la estética es muy bien. Lo único malo hasta ahorita es la retención de café, así que hay que darle unos golpecitos para que salga todo el café. Por ejemplo pones 30g de café y salen aprox 28g-29g, con unos golpecitos basta para sacar el café restante.

Nice design but not working well. Not OK for ESPRESSO!
nice look and design, but limited functionality. - the machine retains a lot of coffee. need to shake it after each use, otherwise blocked completely after a few weeks. - button function "short press for 30 seconds, 2x short press for 60 seconds... etc) does not work. pressing results in random grinding time of 30s, 60s, or non stop. Useless! - adjustment of grinding coarseness is not ok for espresso. it covers all graduations from fine to very coarse, but the steps are too far apart. we have the very expensive filter coffee grinder and were looking for an espresso "specialist". now we have a super expensive filter coffe grinder and this comparably cheap gringer which also covers mostly filter grade grining, and espresso only very compromised. - for the costs of both machines we should have bought a really professional grinder, and not two chique useless decoration items. very dissatisfied.

If time isn’t your concern 5/5
Love the looks and the quality grinding it offers. The only negative thing is the time it needs to grind the x amount of beans. I tried from dark to light roast beans without any problems until now.

Excelente!!!
Cansado de usar un molinillo manual que, aunque funcional, era inconsistente y tedioso, decidí probar el Fellow Opus, con el que no puedo estar más contento. Es muy fácil de usar: solo tienes que dar con el tamaño de molido idóneo para cada receta de café, y en cuanto lo consigues, obtienes unos cafés dignos de las mejores cafeterías. Cuenta con un ajuste rápido gracias a la corona exterior, con la que se puede llegar a conseguir con bastante precisión el tiempo ideal de extracción de tu cafetera. En mi caso, me resulta algo más complicado porque me gusta utilizar 10 g de café para obtener aproximadamente 30 g de producto y, como uso una canasta pequeña, cualquier variación del molido puede afectar a la cantidad de producto final. Aun así, las aproximaciones con el anillo general de molido son bastante precisas y, cuando se quiere afinar más, el molinillo cuenta con un microajuste interior con el que puedes regular cada paso en 10 micro pasos. El molinillo no es muy rápido, posiblemente tarde más que otros molinillos. Mis 10 g de café los devuelve molidos en 30 segundos, tiempo que aprovecho para ir preparando la taza, el portafiltros, etc. Lo bueno de ese molido a bajas revoluciones es que se consigue un resultado muy homogéneo, con todos los sabores y aromas, y lo más sorprendente, sin estática. Todo el molido cae al vaso de recogida; desde él lo pasas al portafiltros y no se queda nada de polvo en el vaso. Cuando el molinillo no se usa durante un tiempo, entra en modo standby, del que hay que despertarlo con un toque en el botón de molido. Al segundo toque comienza a moler durante 30 segundos, y podemos detenerlo con otro toque. También se pueden dar 2 o 3 toques desde el inicio para que, en vez de moler durante 30 segundos, lo haga durante 60, 90... Yo, en mi caso, siempre le doy un toque; muele durante 30 segundos y, si no noto un cambio importante en el sonido de la molienda, le doy otro toque para que termine, deteniéndolo cuando quiero con otro toquecito. El sonido es bastante contenido en comparación con otros molinillos, y la limpieza es muy sencilla porque genera muy poco polvo y el vaso queda prácticamente limpio al volcar el café en el portafiltros. Estéticamente, queda muy bien en la cocina. El vaso siempre se ajusta en su sitio con imanes, y lo único que hay que tener en cuenta es que, si quitamos el vaso y cae algún granito, puede rallarse la base de plástico al colocarlo nuevamente. Yo tengo bastante cuidado al hacerlo porque he visto reseñas de personas a las que les ha pasado, aunque a mí, de momento, se me mantiene como el primer día.
