Fitbit is as easy to use as ever, but the features added to the second generation are too gimmicky to help justify that $100 price tag.

The $99.95 Fitbit Ultra offers the same great features and engaging backend analytical tools that the original model did. Admittedly, though, it's not as fancy as higher-priced devices like the $149 Nike FuelBand and Motorola MotoActv that can sync wirelessly directly to iPhones and Android...

While it would be nice if it had Bluetooth for wireless syncing, Fitbit's ease of use and wide range of features will satisfy anyone from couch potatoes to gym rats.

Fitbit Ultra is a sleek, sturdy, and affordable device that can help you monitor your general physical activity level. It's meant for casual users, not serious athletes.

If you’re a hardcore runner, biker, luger, or anything else, this is probably not the best device. A sports watch with GPS and heart-rate monitor would be far superior.

If you know that you are an active person already, then you probably don't need the Fitbit Ultra. If, however, you are on the cusp of changing your lifestyle, and getting up off the sofa, then this could just be the kickstart you need.

The reason I like the Fitbit, after all, is that it's unobtrusive and I don't have to physically enter information on a small device or start and stop an app.

In case it was not clear: we couldn’t be happier with the FitBit Ultra. It has encouraged and nudged us towards a more active, and healthy, lifestyle.

The Fitbit is a great fitness accessory, but this will require you to remember to use it daily, and to hold yourself accountable to trying to do better ... If you are serious about your health, and need a little extra boost to help you achieve your results, this is a great addition for you.
