08-06-2025This is a very stiff belt. Instead of transfering about half or so of the motor spin into random orbit action, it just sort of locks up and the sander spins up like a non-random orbit sander. If you turn it on and wait more than a couple seconds before appl7ing it to the board, it sands fast, but not smoothly. Not good.
