Anyone Use Woot! (Or Others)?

Is there anyone that has used the woot sight to get stuff before or other sites like that? Did you like the products or are they often defective? I know there are a bunch of sites like that on the web pertaining to different types of merchandise, care to share some that you use often? A weightlifting one would be badass… too good to be true?

I’ve bought some electronics off of WOot and never had a problem. Some of them (cameras) were refurbished, but they work fine still.
