Love this, especially for the price! I debated on spending the money on a fitbit, and I am glad I didn't. This does exactly what I need it to do. It counts my daily steps, heart rate, and tracks my sleep. It's also nice it alerts you to texts and phone calls if you choose. It can do more than what I use it for, but it has my most important need. how much do I walk in a day! I have gotten this wet by accident many times and it's still fine. It is also extremely easy to download the app and connect to your phone. If anything would happen to it, I would certainly buy another one.
