The corner rounder works well. Only complaint I have is the thumb screw for tightening the handle from moving does not move, it is locked or seized up, you can't tighten it to keep the handle in place. This is trouble some because every time you let go of the handle, it slides down in the collar, then when you go to pull it again you have to slide the handle up again to the end of the handle so you have leverage. Sometimes it also pulls right on when corner rounding if you are not careful.
