I bought this watch for me, I really like it because it's light, it connects to the phone. I have "notify me when a message arrives" and "tell me when to go to bed at night" and they don't seem to affect the battery. Other things I like: I can see the screen even when I'm out in the sun.
The only thing I don't like is that the strap is very easy to collect dusty. And, now I can’t connect with my phone, so sad.
