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.

Because black is within the visible light range rather than the invisible light range. The whole point is to remove the invisible reflected light from reaching the photodetector. Or so your white paper claims.

In fact, GOSO works as good as, if not better in some CD players, than NDM. Mechanism of action has not been confirmed, either.

Mine arrived today, will listen before/after, anticipating something good here.  I have 3 disc spinners (in 3 systems), if I hear what I hope to hear I'll request two more sets.
