Per photo, it was allegedly a Porter Cable replacement pad. I'm only giving 2☆ becuase the sanding pad is new. But it is NOT a Porter Cable part (see picture). It does not fit exactly, about 1/3 of screws align exactly (that means 1 screw out of the 3...), but it can be forced to work with Porter Cable sander. I am keeping it because I need it for completing a job. Fingers crossed it won't effect much that pad is not centered due to not exact fit :(
Communication would've helped.
