Mighty Mug

Anyone seen this? Pretty sure a suction cup that when you lift the thing it opens an air valve breaking the suction, but thought it funny anyhow.
I could do without the stupid salesman though, that idiot is going to hurt sales I think.

Can you tell us how it actually works?

I saw these at walmart. They seem poorly made with just plastic liners in the cups. They work by a comination of counter weight and low level suction. No idea how well it keeps your cup from spilling but I was very unimpressed with the quality of them. A decent wide base mug, with a narrow neck, with a cap, like a typical mariner cup, would probably work just as well or better.

I have never seen one, but suppose its just a suction cup, that when you lift the cup it pulls away from the base and that opens a valve and breaks the suction. If so then of course it will only work on a smooth surface. If I guess right then if you grab the base it will not release the suction, and I thought I saw that on the video?
I ordered one off of Amazon when I found out the website wanted $5 shipping, Amazon Prime is free shipping.

Suction does not work on teak or other wooden covers. On the plus side if it falls down the coffee does not get spilled.

Would work great on my teak, its varnished.
