Ok, well, I'm going to dime myself out about my propensity to watch infomercials late, late, late at night when I can't fall asleep (I warned hubby about having a tv in the room, he passes right out, I'll tend to find "something" to watch until the wee hours, it's bad...
) -- I saw one for this product and actually thought to myself that if I ever develop back problems, I'm getting one! (yes, it's a problem, I know, I'm going to work on it...). Anyway, here's a link to the site for it:

Hope you feel better!
