No improvements necessary. A flawless on-line ordering system with an on-time delivery.

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.

I needed a voltage regulator as soon as possible to get a school plane back up. I wasnt able to call in the order until right at the cut-off time. I asked to PLEASE try to get the order shipped that day, and she did. Thank you very much!!
