The Body Check Ball is very useful, especially if you are concern about your health. The device has a backlit LCD screen that displays vital information about your bone density, body fat and muscle ratio. It is easy to use. You just need to hold the ball in the palms of both hands, and then a pair of electrodes will detect your health stats by passing signals through your palms. The Body Check Ball retails for $39 each.
