Anyone have a Fitbit or similar product? I'd like to get one, and all I really want is those three things, to tell time, keep track of the steps and approximate calories burned. I don't care about the heart monitoring, and all the other stuff they can do. It's not important enough to me to spend a ton of cash, as I have been using my phone to keep track, but it burns the battery down, and I need a new watch anyway. Any suggestions/recommendations would be appreciated.
