Review on Enertwist 13000OPM Dust Box Detail Sander For Tight Corners And Hard-To-Reach Areas Wood Sanding by Josh Allred

Needed a sander to follow belt sander and for small crevices and joints the belt sander can't reach. This worked great for the first couple days (about 2 hours/day cumulative), though I found the vacuum and catch bin not super efficient, needed to frequently vacuum or air blow out. The 3rd time I used it, an obnoxious sound accompanied by reduced sanding performance prompted an opening of the case, where we discovered the bearings are already shot and metal debris in the armature. I am a fairly lightweight female, this was a simple sanding of a bench in need of refinishing; the sander was not overworked. Total of about 5 hours function before it broke.
