The first Genie I received had a faulty air pump (would not deflate). I tried to contact the manufacturer, but had no luck. I emailed Amazon, and they put a new one in the mail (on overnight shipping) before I even sent the first one back! I didn't have to go one night without it. I really like the Genie now. Works great even though I have a very thick mattress. I don't think I'll be able to sleep on a flat bed again.
