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.

"...wouldn’t it be more impressive to show us a photo of the supermassive black hole located right here in our galaxy?"
Too late, NDM absorbed it all.
Old Hubble photos of black holes. (And illustrations). I hate to judge before all the facts are in but it appears Harvard is a little late to the game. Furthermore, LIGO Observed very good evidence of black holes two years ago when they observed gravity waves produced by black hole merger. I’d say better evidence, actually.
