This product has a very "toy like" feel. The case is flimsy, the buttons feel funny, just toy-like. It only works when positioned horizontally onyour belt. Seems to work OK, but don't dare drop it or it'll break. The light plastic case has a heavy metal weight glued inside.Why not spend $8 more for the superb Omron HJ-112? The HJ-112 has dual pendulums inside so it counts accurately whether on your belt or in your pocket. And it's built like a tank.
