I love this thread, having made my first ASOTV purchase at the age of about 14... It was the Sweepa, they cleaned a mall in the infomercial and I was sold.

Still have it too, it comes in handy when you need a squeegee. That started the ball rolling and I bought the Ronco Electric Food Dehydrator (still have that too, it works pretty well but is a hassle) shortly after. My parents just loved all the stuff I was bringing to their home.

But they still have their Royal Diamond (I think that's what it was) cookwear that I bought them for Christmas when I was about 17. Take it from me here and now, the **** pills never have and never will work.
So for more recent stuff...
OxyClean- I love it, though it seems not to work as well as it used to.
Hercules Hooks- Really interested in, may have to try those.
Steam Bullet- Just ok, but comes in handy for sanitizing and dewrinkling. (And please, no matter how tempting it is, do not aim it at your husbands butt even from what you deem to be a safe distance. He will have a scar.

Don't ask me how I know that...)
George Forman Grill- Had it and loved it, used it until we dropped it and broke the lid. Still have it though, JIC we feel the need to use it again.
I know there are many many more, will have to think.
