I got mine stuff in today. Well made and fits perfectly for me. From opening the box and insert plates and put it on, that quick. I got the Tustodo carrier with 10x12 front & back curved plates and 6x6 flat side plates.
I spent couple of weeks looking at different manufactures and their pricing (money was a major factor in my decision). AR500ARMOR was the only store that returned my email when requesting NIJ ballistics info on their items. No one else ever returned an email to me.
I wanted to get away from soft armor and go with plates as they last a hell of a lot longer and over time cost less in the long run.
I definitely give them a thumbs up for customer service, as well as prices too..... I even checked on eBay as I usually get better prices on that site.
The deciding factors for me were:
Money/Cost
Ballistics info
Customer reviews
