I've got the Fitbit HR and I love it!! I've had it for a few months now and haven't gotten bored of it yet. I actually only got it for the extra security of the traditional watch band but man I really love the heart rate feature. I thought I would never use it and it was just the extra $20 from the normal charge but it's so helpful. In exercise mode it will tell you your avg heart rate and peak HR so you know to push harder or whatever your goal is. Plus the caller ID and the silent alarm is fantastic! Bought it on kind of a spree because my dad had one and it was such a great choice! My brother is switching from jawbone to Fitbit soon
