I use this tool daily in a production facility, along with the straight model. It's worked flawlessly for over a year now and is frequently used by coworkers instead of their own tool truck models (multiple different brands). Lots of power, very little vibration or noise, and always reliable. Kudos to Astro for making an outstanding product.

Super decent value tool that works as expected. Does take a lot of air to keep it spinning though

My go to took for sharpening garden tools and lawnmowers blades (using the 3M Roloc system). It works great for my needs, seems to be very good quality, and I suspect will last me many many years since I only use it maybe 2-4x power month.

I like the power of them. This is My second one. The crappy thing about them is the tool to change the bit are junk it bends then you'll beat up the casing trying to use it. My first one the gears stripped out inside but that was after 3 years of pretty intense use. I'm hard on stuff. The grip is rubber which doesn't get freezing cold from compressor air. And you can swivel the air exhaust any way you want.

I'm a dealer tech in New England, I'm cleaning rust every day. Caliper brackets, hub faces, you name it. These Onyx tools are as good as the best big name and the price is unbeatable. A big difference is that the exhaust is somehow just barely muffled and it creates this cool little Jetsons noise when you let off the throttle. My shops air PSI is limited to 120 but a tad higher and these would be downright dangerous.

I like these ... a lot.I originally bought the 90 degree and straight shaft kit.They are powerful as well as well made.I liked the 90 degree 204 series so much I bought another one today so I wouldn't have to change out tools and have a burr on one and a 60 degree 2 sander on another.

So far so good. I've tried the cheaper brands with no luck. This stacks up with the expensive stuff.
