Review on Diamond Cutting Porcelain Diamond Stoneware by Jason Epstein

I've had a bit of a drainage problem on my new (well, fairly new) concrete deck. I used this blade in my small angle grinder to cut a small V-groove in concrete. I'm not really happy that there is a groove in the concrete, but I'm very happy with how the blade works. I don't see any noticeable wear on this blade so it should be fine for a future project.
