When it worked, easy to use and effective; Two year warranty but it remains to be seen if it is a genuine warranty

Hopeless quality and reliability; Failed after about four weeks; Worse, it was a present so it's embarrassing; Now I've got the inevitable battle; Avoid if you haven't time for problems

Good value for money i believe, however, i was disappointed that the app that goes with it is quite poor and has all sort of issues. Also, been using it for two weeks and it just does not record sleep correctly, i mean they are way off, i can only trust the deep sleep score because i don't know any...

Not entirely flawless, but incomparable at this price point - even against the newer Mi Band 4. Mi Band 3 is an excellent value activity- and sleep tracker, with a built-in heart-rate scanner. It's fully waterproof and offers extraordinary battery life, plus at-a-glance info on the time, date, weather and important notifications.
