Review on Large Dual Action Hand Pump by Coleman by Andrew Krishna

I bought this for an Aerobed Endura mattress that seems to need a little extra air every few days. (The mattress battery pump lost power.) Coleman - Great value - moves a lot of air. Mine has the inflation outlet on the piston, not the base of the pump, so the outlet moves when pumping - it's a bit annoying, and if you're not careful the pumping action can stress the tube or valve of the inflatable. Tip if the attachments don't fit: Unfortunately, none of the attachments supplied fit. patented large aerobed ring valve. (Note: I'm not deducting stars for this issue since the valve is company property.) I went the MacGyver route: I cut a 1-inch hole in the closed end of a standard-sized canister and screwed it on. Cut the end around the ring from the outside inwards as much as possible and secure with an elastic band. The elastic end was then wrapped around the pump tubing (without the nozzle). This creates a sufficiently tight seal to inflate the mattress to a high degree of firmness. Since I use the aerobed at home and not on the go, I can leave this setup the way it is. If I had to constantly detach/attach the balloon, it would probably wear out pretty quickly.
