I’m new to the pneumatic sander game. I bought one from the auto parts store and my 60 gallon 5hp compressor couldn’t keep up. I found this sander and recognized the name, took a gamble that a more expensive sander might be better with air consumption, and boy it was worth it. This sander is so quiet, way less vibration, and my compressor can actually refill itself without having to stop using the tool. Even the vinyl pad that you stick sandpaper to seemed so much nicer than my other cheap one, able to contour to to surfaces better. I swear the tool cuts faster than my cheaper one. I have very limited experience with these tools, but I have to say that this one was absolutely amazing. I would buy again any day.
