We bought this for our son as one of his main Christmas presents and it was a complete disappointment. After blowing it up on Christmas eve, for which you will have to use a pump as blowing it up by mouth is almost impossible, we found it deflated and collapsed on Christmas morning. It was moved to his bedroom, blown up again to deflate again within hours. Unfortunately we didn't keep the packing it came in otherwise we would have returned this item to the seller. Its a complete waiste of money and would not recommend this item to anyone. My son never got any use out of it and the only thing worthy of it is the bin.
