This is AMAZING! I never used anything before other than a plastic mat with a ruler on it. The sound is muffled tons! I have a cheap Ikea desk and the DESK just echoes in the room, lol, so there's still some noise, but it's not the actual sound of metal hitting metal (hitting metal..?)
I think I stamp much better too! It does take some getting used to, I might lower my desk a little bit because (obviously) my bench block sits higher now and I'm not adjusted for it.
