I used it to finish the side edges on 7 pieces of quartz stone for trim accents around some custom showers I installed. I have used other grinder/polishers but this was a far better tool for my application. What I appreciated most was the lightweight nature of the tool. I used it with a 29 gallon air compressor. This was a little light for the application, if I had a bigger compressor it would have been better (less waiting between passes for the air pressure to increase). But it did the job and no one would be the wiser that I didn't hire this work out. Doing this on my own saved me a considerable amount of money on fabrication and after a few YouTube tutorials I was ready to go. A couple notes of caution - you likely won't be able to use this right out of the box unless you have a barbed adapter to connect to the fittingless end of the supplied water line. This was a bit of a frustration but was quickly remedied with approximately $10 in fittings from my local big box hardware store. Note I also splurged for a 10ft 1/4" water line hose so that I wouldn't have the weight of a garden hose hanging off the end of the tool. With my plumbing all sorted out I knocked out the work in less than 8 hours and general cleanup of the tool was a breeze. Definitely worth the investment.
