Anyone, Anyone, Bueller ? Can't seem to find this info anywhere, seems to me as though the bag needs changing after 1 week , thats not going to be cheap.... or easy to do.
They last a pretty decent amount of time, I mean...it all depends on how much you use it and how you treat the bags. If you are careful with them they last until there is just too much resin built up inside the bag for it to inflate...if you throw them around and shit you will get holes in a couple of days.
