I just ordered four very tiny items for a couple of bucks and you treated me like I ordered much much more. The order got to me in just a few days and all I can say is your company is at the top of my list. Thank you very much. Stan

Received order very quick. I was totally impressed with how well it was prepared for shipment. While a fragile order, it arrived undamaged in any way because of the excellent packaging. Thanks.

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!!
