Review on Guardian EcoGuard Diamond Recycled Charcoal by Eric Williamson

After ordering one under the chair I liked it so much I ordered 3 more. I didn't quite understand why I ordered the big ones (3x5 ), they're a lot cheaper than the small ones, but I can live with that. They're big enough to cut in half and still use anywhere. cut in half and used as a doormat inside and out, leaving one as a spare. Overall I am very happy with my purchase.
