Wow..thats basically all i can say. I bought the cd, then realized that they were playin live like 20 minutes from my house. They put on an amazing show! They closed it with do you call my name, then went backstage. The crowd started chanting, "ONE MORE SONG!!" The drummer came out and started playing again. Then all the rest came back out and played one last song. Ra is underrated and a great bunch of guys. I got my cd autographed by all 4 and i got a picture with them. Buy From One, Duality, and SEE THEM LIVE!! My ears are still ringing.

I purchased this airbed because I wanted to sleep in the same room as my newborn. Yes, I'm one of those paranoid new moms. This bed goes above and beyond. I wanted to buy the AeroBed first because I'm one of those people who hates to buy cheaper items because they usually break or whatever. I'm pretty much a sucker for the theory that expensive = quality. However, I went with my gut and decided to try this airbed having never heard of the company before. Listen to your gut! It inflates in 3 minutes and deflates in about 3 minutes. If you want it to be more firm & allow the air to settle in better, you should leave it in there for about 7-10min. Not a big deal at all. Go do something in another room while you're inflating it. This thing can also handle a lot of weight. When I'm sleeping on the airbed, my husband comes in the room to tell me he wants to sleep in this bed too because it's so comfy. Great Buy!

I looked around before buying an airbed. Saw many options and compare. Many different comments that confused me. But decided to buy this one due to the price and the electric pump. Excellente product, inflates in just 2-3 minutes and last all night long. Easy to store in the morning. 5 star product.
