How can I score the FitBit Alta on durability, portability, ease of use and design and form factor if the damned thing fell off due to a terribly designed clasp and was lost on the third day we owned it? The Engadget review briefly mentioned how difficult it was to operate the clasp, and obviously have to agree. It takes two sets of hands to get it even close to being securely fastened.
The problem is that the clasp works like an adjustable baseball cap, with two small round pins that you push through a series of holes. All of which works fine on a hat when you can see the round pins. But on the FitBit it's reversed, and the strap with the holes is against your wrist, so you can't see if the pins are securely through the holes. And it's difficult to snugly adjust it and still get a finger beneath the strap - between your wrist and the strap - to feel if the pins are through the holes.
This is the second FitBit we've owned. The first generation model had a problem with getting the charging connection securely into the device, and we'd hoped the new Alta wouldn't have similar design issues. Unfortunately it does, or did, since ours is lost.
