I originally purchased the pad from Campmor. I have been very happy with the performance, just worried about it wearing out so quickly. I have 2 other thermarests that are much heavier, but have 3 years of service with absolutely no problems.
Campmor has been really good about returns, I had a problem with a jacket zipper getting stuck the first time out. They sent me a new one no questions asked, and refunded me the amount I paid to ship the item to them. So, if I am to return it, I will go through them.
What constitutes abuse? Sledding? Just kidding... I use my pad fairly gingerly, and it is stored under my bed with the valve open when not in use. I make sure not to slide it around when setting up on leantos for fear of slivers. None of my thermarests have punctured to date.
