Don't waste your money
Absolute rubbish. Firstly you need an electric pump, vaseline and a cotton bud (which isn't made clear) plus superhuman patience and strength to just inflate the thing. Then it slowly deflates through the day and then the time consuming process starts all over again. Three days in and I think it's given up the ghost. This product was clearly rushed to market before thorough testing and refinement. Very disappointing, especially as my children saved up for this.
