The Mi Band consists of the oval-shaped tracking module which has a matte chrome finish and neat, chamfered edges and a(default) black or colourful, rubber band.
With an IP67 rating, the Mi Band is waterproof down to 1m for up to 30 minutes
especially important as it tracks sleep as well as steps. One downside is that both parts are easily scuffed.
There’s no display but there are three LEDs on top - the colour of which can be customised in the Mi Fit app - to show you your progress. For instance, the bottom LED will blink if you’re less than 30% of the way towards your goal.
The Mi Band’s tracking is somewhere in between apps such as Google Fit and Moves and trackers with real sensors such as heart rate monitors. It tracks steps, distance and estimated calories burned as well as providing a timeline of how long you are active each day.The Mi Band connects over Bluetooth.
The Mi Band has a couple of non-fitness features including an alarm and vibrations when you get a call.the Mi Band is gives a 30 days of battery life.Charging is quick - from zero to full in less than two hours.
My suggestion is if you are thinking you might like a fitness tracker and aren’t sure if it will really work for you the Mi Band is a great option to wet your feet and see if a larger investment of a for robust tracker would be worth your while.
