First things first: the inflator. In principle, the idea is excellent: the inflator is included. In fact, it turns out that we must add to it 4 D2 batteries to operate. And what works: we must not less than 10 minutes to inflate the famous ball, with the landmark case that floats around. The ball then: flat, it evokes the silicone breasts, bloated ... too! No rebound, a bulky thing, especially that deflates as quickly as it was long to swell ... when it does not die!
