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.

"Four days without a post anywhere by Geoff, what’s up with that?"
Is that true? It is understandable he does not post here but does he post elsewhere? If not, has anyone heard from him over the last four days? I hope he is well.
Oh no worry he is alive and kicking.
Yes I have had contact with the man.
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.
