This is the 4th generation of Mi Bands I've had, beginning with Mi Band 5. I didn't really like the size switch (I think they made it bigger in gen 8) - as I really liked the slim band that you hardly knew was there. But, I have to say this band feels awfully sleek. And I don't really notice it that much.The band is really soft - they also appear to have made it a little thicker. As I did break 2 or 3 bands over the years, this is probably a good thing.The auto brightness is an awesome new feature - it was always a pain to adjust the watch for different lighting. Overall the look and feel of the operating system is definitely improved. I assume the heart rate tracking is as stellar as ever - Mi Band has always excelled in that area, and been very close to Apple in terms of accuracy. There's a guy on youtube from Germany or Switzerland who has a great technical comparison of different heart rate trackers, and Xiaomi Mi Bands have always done really well there.Sleep tracking has always been not quite as good - but still a lot better than most. For people like me who just want to know "hey how many hours did I get last night" this band will undoubtedly be pretty spot on. Deep diving on your REM, etc - it probably won't rival the top trackers.The biggest problem with the Xiaomi ecosystem has always been how crappy their fitness app has been. I used a 3rd party app for a long time. But the newest incarnation of the Mi Fit app that goes with this watch appears to have finally gotten it right. The app sort of gets out of the way, and gives you what you need pretty quickly. It appears to sync well, and works with things like Strava and Apple Health.I wish I could fine tune the watch OS a little more - and get rid of all the activities I don't do, and just have about 5 or 6. I don't really see a way to do that right now.But overall this watch feels like a pretty decent upgrade from the previous bands, including 8.Highly recommended - probably the best fitness tracker on the planet for the money.

I've had every single misfit since 3. This one by far is the best. Has all the features that you could ever want with the pricing that is still within the mi fit expectations. Fixed all the slump engineering of previous devices.I've had it since it first came out and I'm just now giving my two cents for reviewing it. I easily go 10 to 14 days between charges while not dialing much down for energy conservation.

The media could not be loaded. Great cheap fitness watch option. It cannot display emojis but it does show texts and notifications. Apple app you cannot change the km to miles which is frustrating. Also it does not track sleep perfectly, I find it displays waking moments as rem.

Está es la tercera que tengo tuve la 5 tuve la 8 y ahora la 9 yo las prefiero sobre les Smart watch por qué traen lo que yo necesito para mí son muy cómodas y se ven bien yo no puedo estar sin traerla ya estoy bastante acostumbrado a traerla

Light weight. Bright screen.If you don’t want to have bulky smart watches, this is for you.

Most notably, I have been using the Mi Band to monitor my sleep, and to be honest, it blows everything else out of the water. It's a thin device and very comfortable — I actually don't realize that I am wearing it at times. Sleep tracking: It does a good job of following when I go to bed, waking me up at night and even measures how long I spend in deep vs light sleep.I loved the sleep analysis that came with it in the app It did give great recommendations and advice on how to improve your sleep — I actually found those quite helpful & easy to follow. And it even registers naps during the day, which many more expensive devices ignore.The battery is a beast. I only need to charge it every two weeks, with sleep tracking (of course) on every night.

he tenido el modelo 3,5,8 y 9 y sigue siendo un producto que me gusta mucho, mas refinado en cada generacion

I love this watch. Great value for the price.
