So far so good! It very easily blew up a queen size air mattress and several adult size pool floats! We do not use it often but so far its worked just fine and has been a very nice addition to our camping gear!
The pump worked great inflating our inter tube floats. We inflated them in the parking lot from our car and was able to deflate them later with the pump as well. The pump comes with 3 different attachments which is handy. I have nothing negative to say about it.
