The ball itself is ok, unfortunately could not inflate completely because the manuals supplied with the pump broke down him. Thus, no real evaluation of the ball possible. It is the way it looks: miserable. Constantly she slips from the ball, then goes up at the pump, the hose out and can no longer be used almost. But what do you expect for the price of clever pump .... Will now go only once in search of a clever foot pump, so that the ball can finally do its duty times (I hope)
