I'd still want to see tests. Buy one, put it in a backpack and fill the backpack with sand. Then shoot it with a powerful handgun and see how it performs. Also, it won't stop rifle rounds, which you will need a ceramic or steel plate for.

At a minimum, tell your kid to turn the backpack to the front during a shooting. Textbooks will do a lot to slow/stop bullets. From experience, 2 inches of phone book will stop a .22lr round. Obviously something like a .50AE will still be lethal, see the woman who got charged with manslaughter for killing her boyfriend after he asked her to shoot him in the chest with a Desert Eagle (while holding a book).

I'm not sure if "Ballistic Level IIIA Lab Tested" actually means anything. Since these are probably meant to be sold off to scared mothers, I'm guessing they used as little kevlar as possible to theoretically get to IIIA level and then skipped on the expensive process of actually getting anything NIJ certified.

They could still work but I'd want to see results for myself.
