This is a great sander. The quality, fit/finish is outstanding. It is a little hard to control in the rotary mode due to the high power, so be sure to try it first on some scrap until you get the feel of it. I use the rotary mode for rough sanding, and it does a quick and smoother job. I switch to eccentric mode for fine sanding, or I switch to my Festool ETS 125 which is lighter and easier to hold. The nice thing is that they both use the same sanding disks.
