Restore's Engine Restorer: Work, Whatever, Full of shit?

Saw a commercial for this product and I figured since most of us have high mileage motors this product might work for all of us. Has anyone tried it on their cars? Does it work? Is it full of shit?

I'm kinda skeptical of its miracle compression regeneration... Anyways, what do you think?

its designed to break down carbon deposits and sludge. theres no miracle. if your piston rings are shot or valve seats arent perfectly smooth anyways, it wont help. but it can help if you have carbon deposits on your valves that keep the valves from totally sealing.

kind of like seafoam? It will clean your shit out for sure. But that could be a bad thing at the same time lol.
