Easy to read scale, sometimes shows 4.2 as the default weight, instead of 0. Once you know that, you can figure out your weight. You have to put some other weight / pressure on it, lift up, then it will go to 0. It is so strange. Overall, I love the big display and the blue light, it is a nice thin small size, and I've never had to get a new battery. Seems rugged and sturdy enough that should last a long time.
