Review on Grinding Grinders Polisher Concrete Accessories by David Stewart

My husband used this to collect concrete dust when sanding high spots in our garage. I read many reviews before purchasing and decided to try it. He had to make a small modification to fit his DeWalt angle grinder. The modification consisted of sanding the plastic down the center of the collar to make it fit properly. One of the reviews he read said to tape the bristles because they weren't long enough. It did, and the dust didn't fly out from under the case. The amount of concrete dust collected in the shop vacuum was overwhelming. In use, the housing functioned dust-free. He was very pleased about that.
