If you want a great fitness tracker this is the one to get. It tracks steps, sleep and gives you a notification of incoming calls. Simple to set-up and in the month I’ve used it, it never once lost the Bluetooth connection with my Verizon LG G3.
The battery easily lasts a month between charges. It doesn’t give you a ton of data, but what it does track, it does so very well! You do not need to tell the band you are going to sleep, it must use decreased movement to start sleep tracking.
It also has a vibrating alarm, really it has three so you set three separate alarm times.
