I did some grinding today with dust shroud and it was amazing. I didn't have to wear goggles over my glasses, I could see everything i am doing. It was 99% less dust. The only thing it is much harder and slower to perform grinding and also when you get to curved surface it is almpst impossible to grind without digging in. It is still worth it to have it. I have Harbor Freight cheap grinder it is onle 4.5 amps and it is not enough. Just order Dewalt 4 1/2 11 amps geinder and another dust shrout for my 7" grinder. I have still a lot of grinding to do to get to good bounding surface. I will post pictures in the coming days with progress.
