That thing is pretty powerful. I hooked it up to my 60 gallon air compressor and gave it a whirl. It spins fast and chews stuff with the course disc. It has an all-metal body that looks good and is solid. The switch is metal and has a fuse so you can use it safely. There is a nice rubber cuff on the case to make it comfortable to use and easy to grip. When I cranked it for the first time it spat out a lot of green oil. Well lubricated, that's for sure. I put a filter, regulator and lubricator between my tank and hose reel to keep them well lubricated. trigger sometimes. Just be careful and tune it carefully and you should be fine. The only thing in doubt is how durable it will be over time. However, it is well made, sturdy, looks good and works right out of the box. The price is good with a few accessories included, so I have no hesitation in recommending this tool.
