Thank you very much for the excellent service and professional customer care.
The service was excellent. I can think of no improvements to date that you can make regarding internet sales.
The representative for WBParts was efficient & handled our request in a timely & professional manner.
Tried two other sources, neither of them responded, was all done online, never spoke to anyone.
The response is quick and the price is often very good. We are completely satisfied.
