Mi band 2is realy best fitness tracker and it also chepest price fitness tracker compare to other compitater companies.i ahave using this fitness tracker from last few several months.iam fully satisfied with this band because it can work in any situation and weather conditions .because this band is iso ip67 water resistant and splash proof and dust resistant.but im fewly disapointed with display glaas quality it can be easyly sratcheble and crackable you can see my pics my band display glass surface fewly crack near function button due to small accident .but this price you canot get shafire glass dislay like iphones and iwatches.mi band 2 easyly conect with android ( 4.1and higher) and ios also. Latest blutooth 4.1conectivity provided in this band .so it can connect with smart phones easyly and fast .display is very small compare to other band but it can provide large battery backup and standby time .and its battery life nearly 25 day with regular uses so doesnt need to charge band daily or weekly.heart rate sensore also work well and sleep tracker is very acuarate .i did not understant why it can be track acuarately.
