Ordered for a children's party, the Air Guitar. Look really cool and have the kids also really liked. When quality can not be expected much, however. Already inflation is a tricky thing, at least with technical aids. The guitars are supposed to be reasonably firmly inflated, so that they look good and be fun. To catch the perfect point, is extremely critical and resulted in the worst case with the bursting. One of the guitars was already leaking during unpacking, another it was while playing at the party, in which case no brute force was applied.
Given the price it's a nice party gag, I would buy again. However, the prolonged use should not allow it.
