“We’ve used Proto Part exclusively for over 20 years” actually says it all. No other company provides better quality or more cost effective solutions than Proto Part. Even more importantly, Proto Part, the company and the people, have set an example of both customer and technical support that is absolutely unrivaled. It’s only when you do have a problem on a Friday at 5:00pm that you discover how good the support from Proto Part really is and can appreciate the unique relationship Proto Part has with its customers.
