    Love it

    Item exactly as described. Brand new never used. Had one exactly like it and it kicked the bucket, bought this one to replace the old. Easy to sync! Love it! Get it! NOT a scam!

    Lightweight, choice of 2 bands.

    This is an excellent product recommended by Weight Watchers. It is easy to set up. I can keep track of my steps for the day, enter what I ate, calories in and out. Comes with two bands. Love it.

    Won’t fully charge, won’t sync with app. Looks like I wasted my money.
