OK, so I have to ask. Is this real, or is this a joke?

Thanx clearthinker for thinking clearly. Please let me be more blunt. Anybody who buys this stuff is being sucker punched. It does ABSOLUETLY NOTHING to improve the quality of ANYTHING. Please, spend your money on better equipment. Support those that make an honest living making great equipment for us not these charlatans. 

Another Dilbert Dude who thinks any sound can be fixed with digital
correction including a ceiling riding atop of speakers.. Spend your money to raise your surf board ceiling off your 7ft speakers..If you had a taller room then you could buy taller speakers....Tom

I am not going to buy this stuff.But I find it ridiculous when people present their opinion even without experiencing the product. Of course they are entitled to their opinions - but they may not be valid. And to ridicule someone because they found a positive impact in their system is even more surprising. The differences in how systems are setup makes a huge impact on resolving power and identifying minuscule changes.

Only a complete idiot would claim a product doesn’t work without ever trying it.

I don’t know if it does work, but I have no reason to doubt those who have tried it and say it does. As far as I know, nobody who has tried it has found it doesn’t work.

What holds me back is I have concerns as to how to remove it afterwards if I do not like it. I don't want to end up needing to replace tube sockets, power receptacles etc.

You do realize of course you are talking about mapman, mijostyn, georgehifi, and at least a dozen other highly "respected" members?

It wipes off with ordinary alcohol.

Then don’t put it places it can’t be removed until you are sure. Try on spades, bananas, where it is easily removed. Which once you hear it I doubt you will. But that is always the safest way to go about it.
