Piece of junk. Never buy. It's been sitting idle for almost a year. After that I really needed to check the weight of a suitcase. Put in a fresh battery - just in case. It turned on right on, shown 0 after a second. But as soon as there is any pull on the hook, even the light one of less than a pound it turns off. Tried multiple times with the same result - turns right on but as soon as you pull just a tiny bit on the actual belt it's off. Useless. Way past Amazon warranty so I got 0 use of it - when I actually needed it I've got a dud...
