The price isnt too bad.. But looking at the PDF it appears they only tested the plate against 6 shots of M2AP/30-06
The level IIIA and IIIA+ (didn't know that was a thing) appear to have a decent selection of handgun caliber rounds having been tested.
Other than that they don't provide much information.
Sorry I'm not as up on hard armor ratings and specs.. I recently refreshed myself with Docs hard and soft armor primers.
Edit: Dont really like the looks of this https://www.bing.com/videos/search?q...1&&FORM=VRDGAR
