I saw a YouTube review and it looked promising. In video testing of the "IR" version of this fabric, not only did it appear to perform as well as regular black flock, but it also absorbed the iPhone's lidar sensor. Well, I don't know what kind of fabric they sent me, but even on the simplest check with soft, morning diffuse light from the window, this black fabric not only reflected the light, but shone slightly into it through the shadow of my hand. I even tried it with a regular kitchen light and the same, you tilt it a bit to see if it really absorbs the light and again you can see the reflection of the light well and I waved my hand in front of it and man could see the shadow fully. I'm sorry to say that what I received reacts to light like a regular black herd from a fabric store.
