It's a great product and here's why: my wife and I ordered this air mattress because we needed something to sleep on in our new house while waiting for our regular bed to be shipped. We slept on it for over two weeks and were completely satisfied. The built-in pump is great- no separate pieces to keep track of. The mattress stays inflated throughout the night. With other mattresses I've woken up on the hard floor with a sore back. Every couple of days we had to just add a few seconds of air. The Deflate mode worked fine too. In a couple of minutes it can be rolled up, placed into the included case and stored in a closet. In terms of comfort it's not as effective as a real bed to be sure, but definitely the most comfortable air mattress I've slept on.
