Review on 💎 Diamond Ceramic Porcelain Countertop Technology: Unbeatable Strength and Elegance for Your Kitchen by Kevin Graham

Received this literally an hour ago. I used it to pierce two blocks of glass. While it did an amazing job drilling glass, I doubt it will be of any use after today, as you can see. Most of the abrasive part is gone and the blue paint is completely peeled off. Not worth the money.
