Faulty on/off switch, no replacement
My grinder is hardly used but I have had it longer than the warranty coverage, it still looks new. it stopped coming on and i tested the switch with my multimeter and it is a bad switch. i looked everywhere and could not find a switch, could find everything else but no replacement switch. I called Ryobi and they don't even offer a replacement switch. Because of a cheap and faulty switch my grinder is now garbage. Another concern is Ryobi's lack of responses to their customers on a website with this much traffic.

Junk, Not enough power even to do an easy job.
I bought this to cut and grind a couple of small flagstone pieces with a masonry cutting wheel. Every time I pressed hard enough to grind or cut, the wheel stopped spinning. How it would work on concrete or metal I can’t imagine. Returning and will rent a better one. HD does not even rent ryobi Brand grinder so that should have been my first clue.

Good enough
This is a quality angle grinder for the price. It has its limitations but what can do it does. Probably suited best for a homeowner not jobsite quality. Grinding is fine but cutting seems to be an issue
