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!!

I've never received an incorrect order from ACS, even when dealing with small hardware such as nuts, washers, screws, etc. Shipment is always fast and with reasonable shipment prices for my needs. Even my smallest of orders is processed and ship quickly. I'm a long-time ACS customer and I expect I will be for a long time.
