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.

Can we have pop quiz about obvious reasons?

"I also sold a set of various color pens for coloring the CD, including the data side; that product has also been discontinued for obvious reasons."
I am torn between "CDs are becoming irrelevant so market is shrinking" and "Staples stopped carrying them".

The latest posts on botanics have been amusing. In fact, following this thread is, sort of, pleasant. Gold stars for geoffkait and celander.
And I only bring up phytochromes for their unique special properties, not as a substitute for NDM. It’s the geek in me. Like MG, I couldn’t care less about the mechanism whereby NDM works.
I have not. That is why, despite having doubts, I abstain from saying it does not work. I barely have any CD around (I keep two CDs and three SACDs, in case I ever want to check if my player still works) so it is all theoretical reading for me. Somehow, discussion about the properties of plants seems more reasonable and useful than coloring CDs so I have been following it with more interest.
