Rated 1 out of 5Â by daysofcoleco nice try Ryobi
I liked the design of this grinder. A 4 1/2 inch grinder with a trigger at a decent price is hard to find these days. Usually they have barrel bodies and switches close to the blade. This ryobi was light, easy to use and had a good feel. However, I bought it for repointing my brick house and went through two of them before I bought a much more expensive Milwaukee. On the plus side they have a 30 satisfaction guarantee and both grinders blew up before that expired.

Rated 5 out of 5Â by lewelsvc Good hard working grinder
I had the previous version of this grinder for six years. As a handyman It is used frequently. I finally burned it out after going through four 4" twisted wire brushes to grind the paint off a concrete block wall of a gymnasium. It took three days. I've used it for cutting the tops off fence posts, cutting metal, pointing walls and chimneys, cutting tile, sanding, cutting stone, and many other things. I love the control you get with the handle and trigger. You can work with it all day without getting tired. The key to using this or any other tool is let the tool do the work. Don't force it. You will remove more material faster by letting the tool run at speed and preserve the tool as well. If it starts to get hot either give it a rest or let it spin free to circulate air through it. The new one works just as great and has the advantage of the swiveling handle. With a slight modification of the old case and this one is back where it belongs.
