I bought this on sale for like 10 bucks for my daughters first birthday. Unfortunetly I didn't order it soon enough to use for her party but we have used it several times since and it has been awesome! Nina loved it, she was kickin her lil feet around tryin to stear it and it didn't loose air exept when we went into the cold (live in alaska). But I never had to put more air in and it was made out of strong like nylon/plastic so it didn't crack in the cold either. My 3year old neice loved it so much that she almost fell asleep in it. We had to pry the child out of the thing in the end.
