Mirka DEROS II 偏心砂光機，6 吋，5 公釐軌道

The 5mm orbit on this sander leaves a surface so clean I barely had to follow up with finer grit, and the ergonomic grip keeps my hand comfortable even after a full afternoon of work. It’s noticeably quieter than my old sander, which made the whole job feel less like a chore.

The dust extraction is a game changer—it stayed almost perfectly clear while I was sanding, and the 5mm orbit left a surface so smooth I didn't even need to hand-sand afterward. The grip feels solid in my palm, too.

I've been using this sander on a cabinet refinishing job and the 5 mm orbit leaves a surface so smooth I barely needed to switch grits. The motor doesn't bog down even when I lean into it, and my hand isn't aching after a few hours like with my old sander.
