Mi band 2 is better version for first version. It’s design are good for first. It’s also to much light.when any on wear it to this in hands it’s look pretty good.its performance is brilliant.its battery back up also too much to first version.In one charge it’s battery work more than three days.its screen that much bright that you can see it in also in day light properly.y you don’t need to focus to your eye to see it’s screen.its easily connect with any mobile comfortably.its not taking too much time.U have only one issue for that if it’s screen little big and it’s also look like a watch so people don’t need to wear any other things.
