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. 
Well, they are directional, aren't they? Top surface absorbs; bottom surface does not. Lol
So I received the kit in the mail over the weekend. I was going to initially use the kit with my Oppo Blu-ray SE-83 front-loader player. I bit the bullet and applied the kit to my Jay’s Audio CDT2 MK2 top-loader CD transport instead. The listening sessions are ongoing.
What, he asked of Audiogon's reigning physicist, is a "Quantum well"?
