I recently ordered a needed part using my iPhone on a Sunday morning. Easy quick process and delivery was on time as promised. Satisfied customer

5.0

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.

She handled my questions with amazing skill right away, making sure every one of them received a comprehensive and perceptive answer. Her unwavering professionalism and contagious optimism, which made every interaction enjoyable, were what really stood out.

Products are military grade MIL-SPEC as advertised. I was able to locate #10 locking counter-sunk nutplates when ALL other locations, including Aircraft-Spruce, could not supply.
