He gave me a replacement from a different manufacturer. Now I may be wrong, but I'm sure I checked this (new) bottle with Teresa's and it was the same so didn't expect any problems with her DSMB. I can't check coz I'm up in the Shetlands at the moment. Your right about the back filling. There is a non return valve in the inflation post but it's a bit crude. It's a small, 1/4 inch wide elastic band covering an exit hole on the side of a small post inside the bag. It looks as though the band is too narrow as it gets displaced when you fire off the bag leaving the hole only partially covered. I agree, it is a "nasty little bomb",thats why I get Teresa to fill them. Kevin Pickering kevpix@gl*.co*.uk* P.S. John, we can't make Grrrr's trip as I'm up here for that week.
