I think there's a common fault with these. My refill port is leaking so I sent it for repair, a hairline fracture was found in the refill pin. The exact same happened to my friend's spare air. Also its virtually impossible to remove the cylinder head for the purposes of flying. Nobody I gave it to could open it when it was empty.
