Good job, all tools accounted for, packing and delivery was great. All the tools are high quality. Thanks.

Very pleased with the customer service I get when I call. My Cessna 182 is always needing a little bit of extra LOVE from Military Fasteners. When I call to order parts, your training and customer service of your order takers are the tops.. They understand what I'm looking for and can help me figure out how to order it. I've upgraded my old normal headsets to your reconditioned Bose X General Aviation Noise Cancelling. These are my first Noise Cancelling headsets and we are very pleased...I've come back and purchased 2 more...You are a very professional group! With your shipping location in Atlanta, sometimes, I get things in 1 day or 2 at the most. Thanks.

Brittany was attentive to our needs. We had to source some other products you didn't have elsewhere. We would have preferred to place an order a one place. Will come back and order another time.
