So far so good...
Pros. Price, screen, battery life, features, weight, choice of 'watch faces'. Cons. I'm not a fan of the supplied strap, you can start a workout on the app but have to end it by swiping around on the band until you find "end". I've ordered a 3rd party strap. I have most of features turned to always onon, except, always on display. So the battery appears to lose about 10% a day which I think is pretty good. I've used the MI app and also Strava on walks and they both came out with near identical distances/steps although the MI app only measures kilometres not in miles. Otherwise I'm very happy at this price point.

Very good smart watch for a reasonable price
Great gadget, very easy to use. The battery is really good, dropped only 8% in 4 days. I love the colour (I have the soft pink one). Just tried the activity function and it's quite accurate.

So impressed
After my second fitbit charge 5 died randomly again, I decided to look for something else. Having small wrists there wasn't much to choose from, but this watch is brilliant. It just works, unlike the fitbit. It syncs instantly, changes time zone instantly and the battery life is great. I'm easily getting 2 weeks from it. If your phone is set to date-month-year, then all the watch clock faces do it too. Again unlike the fitbit which forces you to use US format. I can't comment on exercise tracking as I only monitor my steps. I've only had it a couple of months so also can't comment on its longevity, but hopefully it will last longer than the fitbit.

Amazing bang for your buck
After a month of using this I can safely say I'm pleasantly surprised. Besides the annoying fact the date is US format and the strap was a tad annoying (so I purchased an elasticated nylon one) it's without a doubt a great purchase I'm really happy with. For such a cheap price I've compared it to my wife's apple watch and my old apple watch (series 6) I just can't get my head around why they cost so much in comparison. The only thing which I can tell that isn't included (that id actually use) is the ability to reply to texts; let's be real though your phone isn't ever really far away and replying on your watch is fiddly at the best of times. Also want to mention the battery life is astonishing. I always used to charge my apple watch daily but this seems to last for over 2 weeks and still have around 35% to go before I get nervy and charge is anyway. Don't hesitate grab one and don't look back.

Very happy with this
OK I used to have a band 6 and upgraded to a Fitbit so you may not believe me but that Fitbit charge 5 was driving me crazy, it didn't work well at all. In the end I decided to try this. Good reviews and loads cheaper. Well what can I say... This is a great fitness tracker. Its Simple to set up and get started and the screen is amazing. The battery life is excellent even when linked to all the phone functions and I can add information really easily in the app. I have so far been extreme impressed. As well as battery life being great it also charges really quickly too

Useless in summer, turns off in hot weather
Well, it WAS a fine, probably four or five star watch until yesterday, when it simply went to sleep. A glitch, I thought, and plugged in the charger cable. It woke up, all was fine. Today, the same thing. A quick google reveals this is not a bug but a feature: the makers think it's a good idea for it to shut down above a certain temperature and then NOT WAKE UP UNLESS YOU PLUG IT INTO THE POWER CABLE. It is a hardly sizzling 20C here, so this is going to make it virtually unusable all summer. Remember to take the cable on holiday with you, regardless of the good battery life, and if it decides it's a bit toasty on a hike, you're getting out your phone to check the time. Terrible idea.

A reliable all rounder - clear display & timely notifications
The band display is nice and clear and these are nice and reliable for notifications so I'm a fan. The fit is good too for any wrist size. Pro tip: to get a custom background image - open the mi fitness app and go into band display, select the All category option and scroll down to Custom and there you can select a style then tap Edit and select background to set a custom background. (This is what the menu looks like on the iPhone app - Android app is likely easier to navigate). Another pro tip I recommend activating: in the settings options on the band itself, turn on the palm to turn off option and easily turn off the band display off at any time by pressing your palm down on it.

Great tracker, awful strap
The fitness tracker itself speaks for itself really - there's thousands of reviews online which praise it's budget capabilities (lovely screen, responsive, good battery life) but the strap is COMPLETELY USELESS. I literally had to reconnect it (or retrieve it from the floor!) multiple times a day, due the way the strap connects using the black plastic 'nib', and therefore incredibly easy to catch on something and pull apart. Eventually, the nib just disappeared, and I wasn't paying £10 for a replacement strap for a £30 tracker, so returned it. Makes you wonder why a strap with such an obvious design flaw was added to the NINTH generation of this model - surely they had 8 other attempts to perfect it?

Nice batter more and enough for fitness tracking
I have this band after my Iwatch was broken. I realized I didn’t use the full functionality of it, because the watch screen is too too small to do anything complicated. I also don’t need (don’t want to be interrupted by) all the notifications/functionality like using my phone. Therefore, I decided to focus on what I really need, which is fitness tracking. I tried the other more famous band, which looks great. But the battery life was a big concern to me. It didn’t last one day after I turned on all functionality. It might be defective, since it claims a little longer Battery life than that. Besides, I had to pay for some functions. So I switched to this one, cheaper but with longer battery life. The battery life is really amazing. With all functions on, it can last 10 days or more (I never let it go down to 30%). When I have a short business trip, I don’t need to bring a charger at all. It provides enough fitness tracking. By comparing with my old Iwatch, I found that the Distance is accurate , the steps is a little lower but ok for me. The calories are very different (I heard the calculation is different). But it does provide me the relative information for my day to day fitness activities. I have it on my wrist all the time. Charging is also very fast. I like it very much!

Excellent value, great watch
I had the Smart Band 6 previously, and when that one eventually died, I was happy to get the latest one, which was at the time, the Smart Band 9. Mostly I really like it. I keep my phone on silent, so the only feature that I really need is to be notified of incoming calls and texts. Everything else is nice to have, so spending $200, $400 or more for an Apple Watch is overkill when this one is $47 and does what I need. Things I like: - Durability - Water resistant: I accidentally wore it in the shower a few times, and it was fine. - Watch face is not huge like most smart watches. - Color screen with lots of free watch faces. - Syncs fine with iPhone. - Long battery life. - Value, as discussed above. Cons: - One other SUPER useful feature the Smart Band 6 had was that you could use the watch to make your phone beep so you could find it. While this one technically has that feature, there is one critical flaw: If my phone has its ringer off (again, see above - my phone is ALWAYS on silent), then when you use the watch to find the phone, it no longer beeps, it just vibrates. And this is not due to a change on Apple's side since I was using the same phone. - A few of the watch faces are customizable, where you can choose what info you want displayed (steps vs heart rate vs ...). I wish more of them were customizable. Also more watch faces with large print and simple designs for those of us who have bad eyes would be much appreciated. Overall, I 100% recommend this watch. Just verify if it has all the features you need. If so, get it!

Great value
Bought this to track steps and workouts and I'm pleasantly surprised! It's excellent quality for the price. Tracks heart rate and sleep pretty well. Battery life is great so far, I've only been using it for approx 2 weeks. Loses a star as it's not as robust as some of my old fitness bands, I knocked my hand into a door and there is a minor scratch on the screen. I know from experience others held up better with minor bumps and knocks. Although there are many functional and pretty watch faces to choose from in the app, I would like some more customisation with the watch faces.

Awful Watch
I spent 80 dollars on this product and it couldn’t even last 4 months without the wrist band completely breaking. For such an expensive watch to be met with such a disappointment is Absolutely ridiculous. I am never paying again for such a poor quality watch being marketed as ‘premium quality’ after 80 dollars being spent. 80 dollars means it should last for a long time not 4 months.
