I bought this set for my husband and brother for Christmas last year then we ended up buying a different set for the movie cash for the new movie. I went to sell this set at used movie retailer and they informed me it was from overseas and possibly a bootleg. WATCH OUT!!!!!!!!

I ordered 3 of these. They are sturdy, comfortable, and stay inflated. The electric motor in each easily and quickly inflates and (almost) deflates them. The height also makes them feel more like a real bed.However, if you want to completely deflate them for storage, that can be a real trick. I could never deflate any of them completely, so in frustration I cut one open to see what the problem is. A design flaw allows an internal plastic flap to cover the deflation port when they are almost empty. The more you try to vacuum or squeeze out air, the tighter the flap seals the port, sealing in the last bit of air.Now I know, and there's nothing I can do about it, but I feel better after attacking one with scissors...

You do have to remember what station you were listening to but I usually only listen to three different stations and it's easy to switch between the stations on the web site. I also like the sound clip option that is available for many of the songs. If it's been a few days since I've heard the song and I'm not sure about the station I can listen to the sound clip and easily identify the song.I teach an indoor cycling class and have found this to be an invaluable tool for finding great songs!
