Property me this pump, as the product name suggests, bought for my Togu Powerball, since any other pumps could not really fully inflate the ball. Unfortunately namely no pump price has been included with the purchase of a ball. The pump has done its job, the Ball has since been regularly in use. I had never re-inflation. The ball itself, however, has the habit of defomrmieren strongly while sitting, but can not the pump. The problem I know of other Togu Powerball users.
