Love working with this company. Customer service is always so kind and helpful.

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.

Excellent service, parts arrived at my home in UK exactly when you said they would even when you did not have parts in stock when ordered, very prompt reply to my queries before ordering, faster delivery than I would have got from UK.

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
