Does anyone have a fitness tracker they like and want to recommend? I'm thinking of asking for one for Xmas, but am not sure which one I want. I was looking at reviews and both the Jawbone UP bracelet and the Fitbit one look pretty good, depending on if a bracelet, or a non bracelet is preferableā€”I'm not sure how I feel about each, so I'm definitely looking for any feedback on a bracelet vs. a non bracelet.
