Herbie's Mini Grunge Buster

Hi All, Yes, I think I've read some past threads here about the Herbie's Grunge Buster Mat for CD's, all with pretty much very favorable reviews by you all, and today, while ordering some Tube Dampers from them, decided to also order the little mini Grunge Buster.

I'm unsure just how much benefit this small tweak will make, but hoping their claims are accurate. I have used a Blaclight CD Mat in the past. Has anyone tried this new little Mat from Herbie, and how did you like it?
Thanks, Mark
