Useful to have, fragile perhaps?

The adapter is really nice to have if you intend to use one of the coleman portable grills mostly at home or in one place for an extended period of time. BUT mine leaked at the connection point from the hose to the propane tank the first time I used it. I'm assuming it was damaged in shipping, but I'm out past the return window so I'll either try to repair or get a new one. Hopefully yours works better.
