By reading the bad reviews of this product, I have not swollen up this bubble. When I was a child I had a similar ball that swelled with a straw and my neighbors also: they all burst sooner or later but we had had time to having fun. This bubble is delivered with quick inflator battery operated (not included) Immediately received immediately unpacked, inflated and hop towards the garden. Result: 20 minutes expenditure for my kitties. As I did not have too swollen, it is still intact even landing on roses. See over time if inflation mini enough to sustain this article.
