Bought this for fancy dress, reasonable price for what it is. Approximately 2 - 3 feet long when inflated. Can't really go that wrong!
It is easy to blow up and doesn't leak air very quickly, lasted the night just fine. Even if it does leak a bit it's so easy to re-inflate that it doesn't matter.
Took it out clubbing too. For that price it doesn't matter if it gets lost / "borrowed" / confiscated or all of the above.
