We've linked to the Jawbone Up before, but sadly, the original device didn't hold up well over time, and the company ended up pulling the product from store shelves.

Well, the Up is back, and Jawbone is promising that this time around, it got it right. Using its built-in hardware and iOS app, the Up can track sleep, activity, meals and more. It has a built-in alarm and is water-resistant, so you don't have to take it off in the shower.

The wristband is $129, and is up for order now.
