Bests & Worsts Reviews from Amazon

We have tiled floors throughout our entire house, and i get sick of hearing every bit of everybody else's conversations and decided to start trying to do something about the sound. I ordered 1 pack of the white, 1 of the grey. The difference in my office is kind of jaw dropping. I mean, I'd like to think I know a thing or two about something sounding different... and my office sounds completely different dude. I'll probably order more of these little gems soon.
