AMAZING!! The Kauffman family rocks. They helped with parts and knowledge base info with the repair of my 30yo Ryobi finishing sander. They truly went the extra mile to assist me, first time customer, from Jersey. Customer Service is an understatement. They went above and beyond. Thank you for restoring my faith in family owned businesses. :)

Needed a replacement O-ring for a Porter Cable 333 sander. Discontinued by the mfg. but in stock at Kauffman. Thanks for the rapid shipment and for helping get this tool back at work.

Parts got here, and installed. I have not yet tried it, but I see no reason why the sander won't work. I am just impressed that you folks have the parts. I checked about a dozen internet sales companies, and you were the only ones to have the parts.
