I used this product to fix a couple of fairly large holes in my air mattress. So far, it's held up remarkably well. Since fixing the holes, I've used the air mattress on three separate occasions over the course of the past three months (for a total of about seven nights, cumulatively). I'm about 200 lbs and the patches haven't given in or leaked at all from the pressure of my weight. This purchase saved me from having to spend another sixty bucks on a new air mattress.
