I have spent over a hundred nights on mine, I guess. It has never leaked but the valve is just starting to get unreliable. The valves may be improved since I bought mine in 2016. Packs small, easy to inflate, and the insulated version I have has kept me comfortably warm well below freezing. All in all, I have been very happy with it. But it's not very thick, so not the most comfortable nights sleep. That's the flip side of easy and fast inflation. When I replace it I will probably go with something thicker and more comfortable.
