I bought it and suddenly I inflated it in order to see if everything was OK. Then I used it on camping and it didn't work. Some air were coming out arousn the valve. So I asked for the return. The seller understood and it was so nice. It's a good product! Just be very careful when you open and close the valve. I think I was unlucky.
