Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?

This is a set of adhesive-backed thin plastic pieces that one attaches to one’s transport or player disc tray. The disk rests on them during non-spin mode, but presumably don’t touch the applied thin pieces during playback mode. The company says the new Dark Matter pieces reduces background scattered light from reaching the photodetector, thereby improving performance. 

Anyone tried this product? Please specify transport or player if you have and your impressions.

@millercarbon:
Since no one mentioned the science, the LED light is focused and polarized. By design, it takes care of all this "green sharpie"  style nonsense on its own.

Great analogy Elizabeth.
Never even really stopped to think about it that way.

Maybe that's why bees are disappearing?
Somebody told them they can't fly and they listened.....

Yeah, I worry about using these thingies in a magnetically-clamped top-loader set up. Seems like doom and gloom would arise. This sort of post should cause Geoff to arise and speak about the perils.

75 years of scientific advancement does account for something.
