Customer Reviews

With ordering parts, I was assisted by Trisha. Extremely helpful, courteous, and professional. When receiving the items, there was a small discrepancy. I contacted Trisha to let her know, and not only did she and another professional, Paige, work with me right there to rectify the situation. They made sure I received new items in a timely manner, at no extra cost. Taking accountability and being serious in keeping with their high standard product has my respect and future business.

As always, my order was filled accurately and arrived quickly. The one item not in stock in California arrived two days later from another store. Over the years, whether a large order or just a few items,I have received the same quick service. My suggestion? Continue the excellent customer service.
