I have been using mi band 2 hrx edition from past 1 year and my experience using this has been great. It is very cheap costing 1000₹; but offers a lot of features and to be honest the band can even be used as a normal Digital watch, the band had oled display which is mediocre at best as you won't be able to see it clearly in sunlight and also it does not have any settings for the brightness, the band is of improved quality when compared to mi band 1 as I had the problem that the module would fallout of the band but in Mi band 2 hrx edition this was not the case, the band
Is made of hypoalgeric material so it does not affect people with sensitive skin.
Mi band 2 hrx offers various health tracking feature which are essential for people who want to maintain a healthy lifestyle, the readings provided by it are mostly accurate but the step counter can be tricked by moving it in some specific way but that rare and happens only when u do it intentionally. The battery life is good can lives upto the claim of 21 day if you just connect the band to your devices once in a day but if it is kept connected to the moblie all the time then he the battery lasts 10days which is good.
Summing it all up it is the best fitness band you can get for this price range it is must by for people who are getting in fitness regime as a starter device to help them achieve their goals easily.
