sniper, I love my action seat, when I was building my boat, a lot of people told me the same thing and it's true the seat will pop off. The hinges it comes with are worthless. I replaced mine with normal pins from a hardware store ($3) and it works great. I really like how it folds when I transport my boat and there is no wind resistance and I like the small give it gives me when I pull hard on the oars.
For $25 you can't go wrong trying this seat. If it breaks 2 times, I am still better off replacing it than buying the overpriced NRS seat. I've had mine for 2 years now of heavy use. No problems yet.
