Sorry about your bad experience, I hate how that feels. Just my 2 pennies: I bought a used fish cat 4. The og blue one with foam seat and couldn't be happier. Both origonal air cells popped a year apart, after I over inflated them, my fault. When I called they answered the phone right away and in five minutes they took my address and shipped me a new air cell next day, only cause I called later in the day. Free shipping and it arrived in a few days. I would highly recommend these guys. Also they researched and upgraded the air cells with slightly larger ones that won't pop.
