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.

good to hear uberwaltz.  Now that I know he is ok, its kind of nice not having to hear about his wire directionality mumbo jumbo.LOL
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.
'green sharpie nonsense.' great idea  to call it nonsense 'in theory', problem is, it works. So theory' aside, it works. I LOVE to hear all the theories why stuff cannot work, but does. Theory says bumblebees cannot fly. yet they do. (""According to all known laws of aviation, there is no way that a bee should be able to fly. Its wings are too small to get its fat little body off the ground. The bee, of course, flies anyways. Because bees don't care what humans think is impossible." )              
Maybe you need to work on the theory.
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.
