Tell me about stillpoints, please.

I had an isolation demo at a dealer, I'm impressed. Sort Kones are far too tall and ridiculous looking. I feel like my kid would touch it and the amp would tip over and fall to the floor. They did work though. The other version for under a tube amp was more like a set of pucks.

Do Stillpoints replace the feet of my Mc integrated or amps? Or is it a set of pucks that the Mc sits on top of?
