The construction of the bounce house itself is very good. We have used it on the order of 20 times since purchase and there is little sign of wear. However, the only reason I did not give it 5-stars is the carrying/storage bag. It is extremely flimsy and ripped the second time we used it. I am not even sure why it was included other than to be able to say that a storage bag is included. Plan on buying a duffle bag to store the bounce house. Other than that, this is an excellent product that has given many hours of enjoyment to our grandchildren.
