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.

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...

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

Has owned it for two weeks tomorrow. Charged it up to 89% battery and after 13 days of use around the clock I now have 47% battery left so it should last about one month which I had not expected.

There is just something about fitness bands. Everyone seems to want one. It all starts with the excitement for tracking how many steps you walk in a day. That builds up to how much you run on a daily basis perhaps, or how much time you spend in the gym exercising.

Technology can help with your fitness by using an appropriate device.

A barebones fitness tracker for a budget price but its actual accuracy leaves something to be desired.

Inexpensive; Good build quality; Water-resistant; Good battery life

Inaccurate heart rate monitor; Sleep tracking is basic; Fiddly to charge

Xiaomi's fitness wearable is incredible for its price making it the ultimate fitness tracker

So, the Xiaomi Mi Band 3 isn't the perfect fitness tracker. Its heart rate monitor isn't the most accurate, it isn't particularly attractive and the OLED screen isn't all that easy to read in bright conditions. But, you know what, at this price who cares

Amazingly cheap; Includes a heart rate monitor; 50m water proof

Heart rate accuracy not the greatest; OLED display difficult to read in bright light

perfomance is good and light to wear.
