I rarely need an angle grinder so it won't be widely used, but if it's like the rest of my Ryobi 18 volt tools it's ready when I need it. I think Ryobi is the best value for money. It may not be the best, but everything else in its price range is junk, including at least one Craftsman tool that I accidentally bought. I put my money where my mouth is. I have over 25 Ryobi tools, most of them 18V.
