I use the Makita 9903 to sand down 2 loft bed that I build and it work just fine . very easy to use freehand or clamp down to be use as table sander . change the belt sandpaper be a snap . adjust the belt tracker be easy and once set , it stay without drift off . variable speed be simple to use and effective . the release on the saw dust collection bag be not a zipper but a slide device which work nicely .
