Review by Susan S. on 29 Sep 2025review stating Great price extremely fast service
Very happy to with Great Lakes Power tools. Needed new brushes to repair an expensive orbital sander rather than replacing it. Great Lakes Power tools had exactly what I needed at the best price I found anywhere online. They shipped within 24 business hours and I got them quickly.

Replacement was easy and satisfying. There are guides on replacing this that make it a breeze. The yoke comes with the anvil that is prone to breaking. Renewed my 10 year old ratchet.
