Review on AirHawk 2 Comfort Seat Cushion - Medium Cruiser - Inflatable Seat Cushion with Black Cover - Made in USA by Carlos Melendez

although the seat is comfortable, according to others I only give it 2 stars because the seat leaked just a week into my several week trip. And a leak similar to what others have reported appeared at the base of the valve. Inside the bladder is a piece of hard plastic that holds the valve in place. But with daily use and flexing of the bladder, the hard plastic with a sharp edge may hit the bladder and eventually cause a hole. If you're mainly a local driver, 1/2 hour here and there, then flat tire will take a while. However, if you take a long trip and drive more than 6 hours a day, tire failure occurs much earlier than it did in my case. Ok the item is under warranty and they will send me a replacement bladder but that will not help. I firmly believe that it will be a long time before the puncture occurs in the same place. The company needed to reinforce this area of the bladder with thicker material.
