I inflated the Wubble with another pump that delivered, which has the disadvantage of not being able to plug into sector requires big batteries that I had not. At the sight of all the negative reviews, I expected that the ball bursts after a few minutes, so I suggested to my children not to play with in their trampoline, what they did, of course the ball eventually pass over the rough concrete deck and then also in the grass. The balloon is dirty because it is slightly tacky or sticky but did not burst. This is a fairly viscous material that deforms easily, we have not fully inflated. After a good half-day game, now is tidy and has fulfilled its function. My children used it as a balloon but bigger, no football with so or diving on, and in this case, no worries. Therefore see with time, but for a first time, everything is ok !!!!
