Its been a month since I bought the watch. I had been using fitness band before buying the watch. Points below:-
1-Looks awesome
2-Snug fit
3-Great battery life(1-2days) on normal usage
4-Activity tracker is very good
5-Sleep tracker is missing(u can install an app for the same)
6-The charging dock quality is decent(good have been better)
7-Make call through watch and receive also.
8-Watch UI is very goood
Overall I like the watch .Of course Apple products are costly but yes this a wonderful piece of technology. I would say buy if you are using a I phone.
