EXCELLENT WATCH (Minimalist)
I wanted to get a casual smartwatch that wouldn't break the bank, looked casual and dress-down professional, and had great features. Check. Check. And Check. This little gem is awesome. I am especially happy that it connects to my health info and I can track my steps and heart rate. It has a great easily readable display (for me that means without using my readers). It looks like a bracelet and I have received many compliments about its size and look from others who have since bought their own. It fit nice and snug and the band is of good flexible quality. I never take it off and just wear it in the shower (it is water resistant!) and it just keeps on going for days and days without much reduction in battery (really excellent battery life). Seems like it will last for some time. Really happy with this purchase. Getting the new model (2025) as a gift for someone else!!!! ... show more

12 MONTH REVIEW
Wife writing. It has been a year of me having this watch. It's insanely useful for sleep tracking, as it tracks the quality of my sleep and the different stages. The app even has advice for sleep schedules and health advice given by accredited institutions; THAT'S INSANELY valuable in this day and age. Not only does it record my heartbeat, my steps, sleep and calories, but it also has insane customization features. It connects to my phone across the house, and anytime I have ever lost my phone, I have been able to press a button on my watch in order to locate it. It's also non-intrusive and cute. I never have to worry about it ruining my outfits. Because this watch is Chinese, I can order different, cute watch straps on relevant websites where they are cheaper, instead of the dropshipped price. I even garden outside, and I can still check my watch in the harsh sun. It's perfect at daytime and nighttime, because it adjusts the screen accordingly. You can even put your hand over the screen and it'll turn the display off, saving you the trouble of it being on. I love this watch more than anything. The screen does get scratched/banged up over time, I will say, but there are ways to prevent this. I do a lot, so it's seen some things. ... show more

Great fitness tracker for the price. Easy to set up, comfortable to wear, and the battery lasts a long time. The display is bright and clear, and the health tracking features work well. Very happy with this purchase!

A step backward since previous generations, but still a well-designed full-featured option.
For full disclosure, I am comparing this product to the Xiaomi Smart Band 5, which I bought and used for about 4 years. I've kept up to date with the various advancements in the smart band line over the intervening years, and there's really been nothing to make me want to upgrade, and the Smart Band 5 kept on going all that time. I primarily use the Smart Bands as watches (obviously), step trackers, and heart rate monitoring during my runs. The feature that finally pushed me to get the Smart Band 9 was the adaptive display brightness, which is a first in this line. When I'm running with the band 5, it is typically too bright to read the display, so I can't easily set my cadence. The Smart Band 9 definitely works in this regard, however there are several areas where the performance has regressed versus the 5, at least for my use case. Step tracking: The Smart Band 9 records, on average, about 30-40% fewer steps than the Smart Band 5. It doesn't seem to register short sequences of steps, or steps when I'm not moving my arms as much. Comparing to step tracking on my phone, I'd estimate that the Smart Band 5 tracked about 15% more than Google Fit alone, and the SmartBand 9 consistently tracks about 15% fewer steps than Google Fit alone. And since my employer health plan rewards step tracking, this means I need to work harder for the same reward. App: The Smart band 9 uses Mi Fitness as its Android Application. This is a pretty good app. You can define which applications on your phone can send notifications to the Smart Band, and set up a Do Not Disturb schedule, and alarms, and everything else you might reasonably expect. There is one confusing feature that I had to turn off, called DND Sync, which is supposed to synchronize Do Not Disturb with your phone. I found that it just turned DND on my phone on, even when the band was out of DND mode, and that I had to manually turn it off on my phone. I'm not sure of the intended use case here. Calorie tracking is weird. It definitely doesn't calculate full passive calories (~2000 per day), but doesn't seem to full calculate active calories right either. It consistently records in the region of 700-900 calories for me, more or less regardless of activity level. For a time, Mi Fitness didn't integrate with Google Fit. Thankfully, that has now been resolved, so steps and activities sync from Mi Fitness to Google Fit pretty seamlessly. I was used to using the Zepp Life app with the older Smart Band, and this had several stand-out features that are missing from Mi Fitness. With Zepp Life, I could export my workouts in GPX format, so I could use different apps (Strava, etc.) to track and share. This is not possible with Mi Fitness (from my research it may have been possible once, but they removed the feature). So in order to use the heart rate monitor feature, but also share my runs, I have to track my runs using the Smart Band as well as an app on my phone. Secondly, I used to be able to share the HRM data directly from the band with my phone over Bluetooth (I assume), so my running app could directly access the heart rate data from the Band. As far as I can see, that feature disappeared. So now I need to wear a heart rate chest strap for my running app, as well as having the live heart rate data from the band on my wrist. Again, nothing drastic, but a definite step backward over four years of development. The quality of the band itself is very good. I get this thing wet at least daily, and it hasn't objected once. I use it with HR turned off except when I run, to maximize battery life. It's life isn't as good as the Smart Band 5, probably 2-3 weeks. A nice feature is that, as soon as I start a fitness activity on the band, the heart rate starts tracking. I use a third party strap, and these tend to fall off if I hit the device at just the wrong angle. The original strap has a metal latch part that probably alleviates this, but I'm not a huge fan of the feel of silicone on my skin. I've stuck with the default screen, which provides enough info, without being overwhelming. The device itself is understated in appearance, and doesn't draw much attention. So overall, compared to the version I was used to, I'd give it 3 stars because of the annoyances I've outlined. Compared to other trackers in this price range, though, it's a well-featured, minimalist-designed, watch that does most of what you'd want without excessive complexity, so I'll give it four total. ... show more

Simple and reliable
Bought this for my 85 yr. old mother. She loves it. It helps her keep up with her heart rate and oxygen. She especially likes it to keep track when she is sleeping. Great buy!!

Amazing Technology
I have had this product for a week now and I am love it. I was hesitant at first to buy a smart watch because of the accuracy, expensive prices, and another screen to distract me. I turned off the call and text notifications right away so I don't have the distraction. The price is amazing for the capabilities. It actually has more capabilities that are useful and make my everyday life more convenient. I really just wanted it to track my sleep and it does a great job! Specs that I like: - battery lasts for days. I haven't even drained the battery yet because when it gets to 80% after two days, it only takes 20 minutes to charge back! - display interfaces that you can change and personalize - real-time data of heart rate, sleep data - which is accurate to the minute I wake up. - can take pictures and video by tapping my smart watch when phone is on tripod - timer - quiet, vibrating morning alarm clock - can pause or forward music playing on my phone from watch Downsides: - the app did logout of my profile unknowingly so that erased my data overtime (maybe I did something wrong here) ... show more

Worked great for 2 years, time for an upgrade!
Works great, but after 2 years the brightness suddenly started to fall off. Apparently the LEDs have a lifespan, sadly. Fortunately it did so just in time for their version 11 Band to be released.

Not a Good Fitness Tracker, Despite So Many Positive Reviews
I'm returning this tracker to Amazon. In over 4 days of Smart Band 9 use, testing its readings against a Fitbit Charge 2 and a Fitbit Blaze, I've experienced several show-stopping discrepancies that, for me, have me returning it: 1) Calories are nowhere near correct each day. This tracker records zero calories expended from midnight until I get up in the morning, a totally incorrect measurement since the body expends energy even at rest. I had hoped that turning on the Advanced Sleep option (tracking heart rate and REM sleep) would correct this problem, but it did not do so at all. 2) I don't keep the tracker paired to a smartphone that I carry: instead, I return to a stationary tablet where I sync the data. I don't care about GPS tracking, etc. This morning, I forgot to start a Walking workout alongside the Fitbit I was wearing; I hoped auto-detect of my walking exercise would provide some type of data. It did not; no walking workout was synced to the app. When I dug deeper in the "Workout" section of the app, I found a way to add the walking workout and its duration, but was unable to edit any of the variables (like calories) in the workout. 3) The tracker does not come with any type of useful user's manual. In addition, the app itself doesn't link to any more comprehensive user's manual. So users are left to fumble around trying different options on the tracker and the app to customize the tracker. For example, I was able to add widgets as quick access to the typical workouts I do (out of the dozens available) and delete widgets I had no use for but I had to discover that on my own. 4) For a "Global" model with US as a location, the inability to enter English units vs metric was a real problem. I've been using fitness trackers for 18 years. I don't want a fitness tracker to be an extension of my phone, music player, or wallet. I want basic fitness tracking functions to be measured on the band itself and not require constant connection to a paired phone (or in my case, a tablet). While many people may find these features very convenient, I don't use them. In fairness, the battery life was the best I'd ever seen in a tracker. When I did a factory reset for returning the unit, it had at least 85% battery remaining. Again, this was using it for fitness tracking only: no constant communication with phone. ... show more
