Here's a video. The derp starts early, so you don't have to watch the whole thing; I sure didn't.
Here we have the classic YouTube Gun Enthusiast Review of a product that anybody with a shred of knowledge about terminal ballistics, or even just basic hands-on experience of shooting things, will realize has some serious flaws built right in to its basic concept.
How does dumb stuff like this survive on the market? (And the hypetastic claims made about this junk are tame compared to the supposed abilities of some boutique BBs in the past.)
Because a lot of people are buying a gun as a fetish. And by "fetish", I'm not talking about the kind where you hang upside down covered in Saran Wrap while a midget in a clown suit throws pickles at you while yelling "Verboten!" but "fetish" in the anthropological sense, where certain powers, in this case strength and protection, are attributed to an inert object.
The gun is no longer just a tool for making holes in things at a distance, but a magical object that projects strength and wards off danger all by itself, and you can buy a power booster for it in a blister pack for only $24.99!
A gun doesn't keep you safe, okay? Guns don't "save lives". Guns don't save lives in the exact same way they don't kill people. A gun is a tool you can use to help keep yourself safe.
This seems like a good place to link to Kathy Jackson's timely "8 Ways To Spot A Bad Self-Defense Product Before It Kills You" essay.
Like the Romans used to say: "Caveat emptor, baby."
