This a fine quality machine. It really is very basic and quite simple in its design. Although not as refined as some sanders out there this unit does one thing well. SAND.The ability to adjust the speed is a must on any sander. This tool will easily withstand the daily rigors of loading and unloading your work truck. I do recommend upgrading the sanding shoe and I wish porter cable offered that as a standard. From the rugged american craftsmanship to its simplicity and fair price this tool is a big hit. Two thumbs up on this one. Now get out there and sand something.
