Let me start by saying this Retek angle grinder is a solid choice if you're already invested in the DeWalt 20V MAX battery system. I've used it for everything from cutting metal pipes to grinding down concrete edges, and it holds up surprisingly well for the price.

The brushless motor is no joke - hitting 8000 RPM feels just as powerful as my corded grinders. I did notice it gets warm after extended use, but adding some lithium grease (like one reviewer suggested) made a noticeable difference in both temperature and noise levels.

What really shines is the versatility. The three included blades handled my weekend projects flawlessly - cutting rebar, smoothing welded joints, even polishing some old patio furniture. The adjustable handle is genius for awkward angles, though I wish the safety guard didn't require a screwdriver to adjust.

Battery life is decent with my 5Ah DeWalt batteries, but like any cordless grinder, keep spares handy for big jobs. The battery indicator is handy though not perfectly accurate - it'll show full until suddenly you're at one bar.

My biggest gripe? The finish isn't quite DeWalt-level. There's slight gaps in the housing that collect dust, and the power button feels a tad cheap. But considering it's half the price of name-brand alternatives, these are forgivable trade-offs.

Final verdict? Perfect for DIYers who need occasional cordless grinding power without breaking the bank. For professional daily use, you might want to invest in the real DeWalt - but as a backup or light-duty tool? This Retek delivers impressive bang for your buck.
