Rated 5 out of 5 by from Fitbit Addict Careful!!! I have not stopped walking since I purchased this Fitbit almost 3 weeks ago and 80 miles in, 20 lbs. less. It is a challenge but with the positive reinforcement it makes it easy to walk it out. I have also taken a shower and forgot to take it off, still works great. This is the only waterproof Fitbit out there, which is the primary reason I purchased it. Got to get back to walking, goals have to be met.

Rated 2 out of 5 by from What's the Point? This particular model is not that accurate and doesn't really offer valuable information. Each time you move your arm, it counts it as a step. I was sitting on the couch and it said I took 87 steps in the hour. I adjusted settings and still, not accurate. I really didn't want to spend the money on this, let alone get a more sophisticated, more expensive model, but when I found this model to be pointless, I decided to get the Alta HR, which tracks heart rate and sleep in more detail. I love it. Darnit! I just wish it wasn't so pricey!

Rated 5 out of 5 by from Great upgrade from the Flex I bought this to replace a Flex that had died. I was also very interested in the waterproof feature, as we swim a great deal during the summers. I love that it's slimmer and less obvious than the Flex. I had a lot of trouble sleeping with the Flex on, as it's bulkier and actually created a scar on my wrist from sleeping on my arm. This is much easier to maneuver. It's also less conspicuous to wear. I don't feel as self conscious wearing it 24/7.

Rated 4 out of 5 by from This is exactly what I am looking for. I think some of the reviewers that say the Flex2 doesn't have a lot of features. But if you remember, the original Flex didn't show the time or your steps either. My reason for purchasing the Flex2 was so that I when I want to wear my regular watches, I won't lose my steps...LOL. The design of the Flex 2 is a little sleeker than the original Flex and shouldn't look too odd on my wrist next to my watch. Just for the record, I am a FitBit fan, I own the Flex, Charge HR and the Blaze. :) I also was contemplating purchasing the Apple watch and I can stay connected with the FitBit community and challenges (Daily Showdown & Workweek Hustle) with the Flex2.
