I waited two months to write this review because I wanted to see was in use. My daughter just over three years and take great pleasure in this inflatable structure. And it's more reassuring for us that a single bed or it could jump and roll forward. What is unfortunate in fact it is the product description on Amazon that I find incomplete. because apart dimensions, nothing explains that there is a book of 300W wind tunnel and it is a little noisy (like a vacuum cleaner without bag about 1st prize) Then, the external dimensions, but it worked OK not say how many children can play (while everything is on the package!) There is indeed mentioned that 2-3 children can play as long as the total weight does not exceed 90Kg (it's not bad !!!)

I made a video, I'll try to post here. to buy without hesitation. Update after 2 years and a half of use. We go out just a rainy winter or use the trampoline was not possible! The bouncy castle was happy in the bedroom. Use with children does not degrade the castle. It is still in very good condition! So again I can only advise you this. Bravo Updated in March 2015, the game is a little less often used but still functional, to believe it is indestructible!
