Recently purchased this product. We have only used it once for family that came to town to visit. Really liked the feature of changing the level of the air depending on how a person likes to sleep. Also like the fact that it filled up very quickly. I strongly recommend for at least first use, to follow the instructions to fill it with air a few days in advance. The bed did deflate a little overnight and I filled it again. However, the next night it deflated a little again. So I opened the valve completely deflated the bed completely and then re-closed the valve and refilled. It did not deflate after doing that. My house guests didn't have a problem with it and they used it for 3 days straight. Also enjoy the fact that it came with a carrying case and it packed up to a decent size for storage. Very good product for first try!!! Hope to use it again in the fall and don't anticipate any issues! Good purchase overall!
