Good. i get it now I bought this in addition to my belt sander, a Makita random orbit sander and a hand sander. This is a great addition and now does about 60% of all my sanding work in my workshop. Don't panic the first time you use it. that's a different matter. My first reaction to this was. "WTH, it's just a drill with a rotating pad on the end." So I tried going slow with a trigger. The tool heats up quickly. So that's not how this tool is supposed to be used. So I got a good grip on the handle, pulled the trigger at full speed, and placed it on my end face cutting board that I was making. Wow, once the instrument gets into its rhythm, it really sings. He has a small orbital concept. This tool is designed to run at full speed all the time. What the tool does is independent of the trigger setting (speed). It all depends on the grain size. If you have this tool you will need to buy a large pack of paper 80, 120 and 220 (that's 8 holes). 80 skins a grizzly bear! Align the workpiece quickly. 120 will smooth things out. and 220 lays on polishing. 220 made my end grain cutting board glassy in about 30 seconds. That was incredible. Does exactly the same as my random orbital sander (which takes the same paper). but it makes it much faster and more efficient. For more detailed and slower cuts I will continue to use my Makita orbital sander. This is a great tool. but a star is missing for every anther.
