WONDERFUL
I just miscarried. During what seemed like the longest time to recover, I spent a great deal of time researching ovulation strips, just trying to move forward and get trying again. Knowing that I wouldn't have the diligence to test only on my most likely days (especially given that after a miscarriage the menstrual cycle is usually abnormal for 4 - 7 weeks or more), and that I knew I'd be testing twice daily (which I REALLY recommend - my positive lasted only about 9 hours and I would have likely missed it doing once daily testing!) - I did not want something expensive. Don't worry about what others are writing - that they are somehow complex or misleading or lack instructions. First, there are instructions provided and they are more than adequate. They don't cover the literature of menstrual cycles, but so what. Dunk them in a cup of urine for the # of seconds indicated, lay the strip on the cup and although I found the result after about 30 seconds doesn't change much over 5 minutes - or really ever - read in 5 min. When you're getting your LH surge, the strip will turn as dark at the control, and quickly. You can save all your strips if you're obsessive like me, taping them to a paper, if it makes you feel better. Some people getting increasingly dark results until a true positive occurs, some will not. Regardless, for the following reasons I recommend them: 1. It worked. I'm pregnant after testing for 2 weeks. ! 2. Cheap. 3. Easy to use. 4. I found them to be reliable. Good luck, and wishing you lots of success! (And if you're like me and just miscarried, hang in there. Not everyone will ovulate in the month following, but some will. You'll feel better to just do this test twice daily. You won't miss an ovulation. I tested at about 11am and 8pm every day. The LH surge [which this test detects] usually happens mid morning to afternoon, NOT first thing in am. So don't bother testing first thing in am. )

No more "Where's Waldo"!
These little strips are the most amazing thing! Browsing online you can find many types of ovulation strips and machines all ranging in prices from 30 bucks to 250 bucks. Some people opt to go with the little hand held machine to detect ovulation but really when you think about it closer the machine STILL needs ovulation strips so you're paying an astronomical price for some digital read out (plus you still have to buy strips), I'd rather save myself 230 to 300 bucks and just pee on a stick and look for 2 lines, it doesn't get any easier than that. These are very basic and very simple little thin strips. You fill a dry, clean and empty cup with pee, dip your stick in for 3 to 5 seconds and wait. They are very cheap, very affordable and in the long run save you a ton of money. They are small and don't come with excess packaging to bulk up your cabinets in the bathroom. You can be a pee-a-holic and not go broke with these. I love the added incentive of getting not only 50 ovulation sticks but 20 pregnancy tests as well for rounding up 22 bucks or so. In any given drug store I've paid for just a pregnancy test 23 bucks, how silly is that? On a more personal note to anyone wondering the use of these ...some women have periods that are all over, that don't come like clock work on the same day every month which makes guessing your fertile time near to impossible and these really help nail down your ovulation time. Every woman's body is different and while the general idea is that you ovulate 14 to 16 days after your last period that isn't the rule of thumb and it's not an exact science. Every woman (minus those with reproductive issues) ovulate every month just telling when is the hard part. If you are serious about TTC then I HIGHLY suggest these. Some additional information: Once you pee on these and wait your 5 minute time frame you may see 1 of several things. 1 line is negative for ovulation, 1 solid and one faded line is also a negative, you are NOT fertile until you see both lines dark and clear as heck. A weak second line is a *negative*. For those who are in it for the long haul these internet cheapies will save you a lot of money and work flawlessly the only complaint I have is my last batch I ordered has some broken and falling apart but they are so cheap and you get so many I didn't really care too too much I lost some but it's worth noting for other potential buyers.

MuvaMeaux approves!
I purchased this in hopes of getting pregnant back in 2022/2023. I went in blind and uneducated on getting pregnant. It’s not as easy when you are trying to get pregnant. I used two apps to help track my cycles(Clue & Flo) and bought this particular brand in helping me track my ovulation. It was indeed a process and using it helped me so much in learning myself. I also tracked my bbt which is another commitment but it was made. After three months of tracking I finally caught my peak on both apps predicting peak on the same day. I tested twice, my first pre and around 2pm and caught my window on time. I ended up pregnant on the first try and now have a one year old daughter. I plan on purchasing this exact kit again to help me with baby #2. It is indeed a process and it does help, it doesn’t give you the time of window but that’s the point of you getting to know your body. You can’t just rely on this product to give you the exact time, it give you the clear understanding of when it’s time to make a baby. Our bodies will do the rest and it’s up to our bodies to accept the sperm. This is a great product if you don’t want to spend tons of dollars. Incorporate other things to also help with learning yourself and give yourself grace. It is perfect timing for everything.

I Swear By These Test Strips!!!!
Let me start by saying it takes a lot to motivate me to write a review of a product. Before purchasing these ovulation strips, I read a lot of the previous reviews, debating whether or not I should waste my money buying these things. I was already two months into tracking my basal body temperature (with erratic results), trying to figure out the number of days in my cycle (35!... I know TMI), and just praying to God I was estimating my ovulation days correctly so I could get pregnant. But when you want to get pregnant, you want it to happen immediately! This rationale and impatience led me to purchase these strips (plus, they are SO MUCH cheaper than the name brand competitors). I was skeptical, at first, but persistence is key!!! You need to test your morning urine when you first wake up. I used small, disposable plastic bathroom cups to collect the urine sample each morning before I went into the shower and when I came out the reading would be there. It's so easy. You just dip the end of the strip in the urine up to the line and rest the strip on the lip of the cup. I had no problem identifying a positive or negative reading. The lines were clear and not ambiguous at all! On the days when I suspected I should be ovulating, I tested morning and night, even though they say to only test in the morning. The night readings helped me to better determine the 24 hour window of ovulation. Using these strips, I was able to first track my ovulation for a few months and then pinpoint the exact date of ovulation going forward. Mind you, it still took us five months to conceive, but I truly believe these strips really helped me to figure out my ovulation schedule over time. Well, the rest is history... I'm looking at a beautiful one month old baby girl that I prayed for each night. I plan to purchase more of these strips to begin tracking again for my second baby. My advice to anyone thinking about getting pregnant... start tracking your ovulation schedule now, so when you do ultimately want to get pregnant, you will already know when you are going to ovulate and you won't have to wait several months to first figure it out. Good luck!

No Complaints, But Just So You Know...
First and foremost, I approve of this product and it has served its intended purpose. I am not a doctor so I cannot 100% validate the product's effectiveness, but it has easily provided a consistent date for each month's ovulation (That date falls within a 3-5 day window and the kit nails it down to the specific day). It is a simple strip (like the pH test strip used in garden/school/science) that one pees on first thing in the day. Easy enough, mostly, and then I leave it in a jar to do its thing for 5 minutes. The signal indicated has been easily identifiable so no problem there. Because we have been trying to get pregnant for awhile now and we've been using the strips for close to 6 months, I cannot give this product 5/5 stars. That's not a condemnation of the product but just an inclusion of all possibilities for the reason we've been unsuccessful. Part of that is the product is contained in a clear, quart-ish sized bag with a barcode sticker and that's about it. No box, no instructions, just the strips. I know, not a big deal, but it does feel like something bought out of a guy's truck at a carnival. Or manufactured in a churning factory, dumped into a plastic bag, stamped, and shipped blase. It's my imagination, but at this point my frustration has rubbed me a bit raw. I have ordered a lesser amount that was contained and shipped as if I had picked it out on the shelf of my local pharmacy; the contents of that standard box and this product were identical. In its presentation, this particular 50-count product merely comes off as a bare essentials transaction. From my experience, the price is right and I have no substantial complaints.

Awful brand
These are awful 😂😂 the control line is always nice and dark but the test line is very thin and almost fuzzy… these used to be so good but they must have changed the formula…if you look closely, on the test line.. the right hand side is fuzzy and not clear making the line look thin.. I’m going back to easy at home…just so frustrating when you have spent years trying to convince .. I’m on meds to help and i feel like I’ve waisted a month using this brand.

Easy and inexpensive! Couldn't ask for more:)
My husband and I are trying to conceive our second child. My cycles have never been regular spanning anywhere from 30 to 42 days for cycles where i do ovulate, so ovulation tests are very helpful for me. When I got pregnant with my daughter, I had been using the store bought ovulation tests which only had 7 in a pack and were difficult to read. Those ones did detect my surge, but I did second guess the test line for a while, as it wasn't crazy dark. When I first used these strips, I had several results that were pretty dark and I spent lots of time over-analyzing them and comparing to photos of other customers' positives, as well as googling if anyone had positive results that weren't really as dark as the control line. It turns out, those were all negative. When I got my for sure positive surge detected days, THE TEST LINE STARTED TO SHOW BEFORE THE CONTROL LINE AND GREW DARK AT THE SAME SPEED. So I realized, all the ones that looked like they could be positive really weren't because it took longer for the test strip to get dark on those. Now for what I consider the bummer about LH surge testing... When a surge is detected, it doesn't necessarily mean you will for sure ovulate. Last cycle I had a very obvious surge, started testing for pregnancy like a crazy person two weeks later w/o a positive ever. I did some research and found that you can have a surge that isn't quite strong enough to kick the egg out. So that was disappointing. That cycle ended up being 63 days long and only ended because I started taking a vitex supplement (which I can really recommend for ladies with random cycles). So this month, after taking the supplement, I have had a VERY obvious surge on day 17 of my cycle. I really recommend keeping your strips for the whole month and labeling them so you can compare. Working off of memory or pictures is a pain. Be sure to hold your pee for 2 hours or so and don't worry about the whole room temp thing. I will update in a couple weeks if I become pregnant. Good luck to all!

Hands down the most reliable ovulation strips I’ve ever used
I’ve tried at least 6 different brands of ovulation/LH strips over the past 3 years (Easy@Home, Premom’s own brand, Clinical Guard, MomMed, Pregmate, you name it), and NOTHING comes close to the consistency and clarity of Wondfo. I keep these in a bin on my toilet, and test 1-2x a day starting on CD5. These are now the ONLY strips I will buy. Here’s why: • Insanely consistent results cycle after cycle. My LH surge always looks exactly the same — a gradual rise, a blatant dark-positive for 24–36 hours, then a sharp drop. No random faint lines that leave you guessing like with some cheaper brands. • Super clear dye progression. Even my low days are almost snow-white, and my peak is unmistakably as dark or darker than the control line. No squinting in weird lighting needed. • Works perfectly with the Premom app. It reads them accurately every single time (auto-aligns, no “invalid” errors like I used to get with other brands). • Excellent value. 50 strips + 20 pregnancy tests in most combo packs means I’m never running out mid-cycle or paying crazy prices. • Individually wrapped, so they stay fresh for months (great if you have long or irregular cycles). After too many months of second-guessing evaps, dye runs, and inconsistent surges with other brands, Wondfo has made trying to conceive so much less stressful. If you want strips you can actually trust, just get these and save yourself the headache. 100% converted for life. Highly, highly recommend!

Hit and miss
Bit hit and miss with these strips. I’ve had to use couple of strips on same sample as one wouldn’t show anything except for white instead of the purple dye. Recommend try different brand

Not a fan
I used these opk's as well as easy@home. These strips never seem to show a test line. Even when my blood results and other strips were positive for ovulation these ones never got dark or showed a positive. A few of the tests have also been faulty, they ever bleed pink all over or no lines appear at all when dipped. I wouldn't purchase again

Not Accurate – Very Disappointing
I was disappointed with these ovulation strips. I tested three strips at the same time using the same urine sample, and each one gave a different result. One showed a half-dark second line, another showed no second line at all, and the third showed a faint second line. The inconsistent results make it difficult to know when ovulation is actually happening. I wouldn’t recommend this product if you’re looking for reliable ovulation testing.
