The guy in the video was way too comfortable pointing a loaded gun at his hand. I've seen that in videos on the NAA minis, seems like people who would normally follow basic gun handling rules toss them out the window when they have a tiny gun.
But yeah, practical-wise there's nothing this thing can do that an NAA mini can't do better. Reminds me of the Taurus Curve, as I believe the target demo is people who aren't experienced gun owners and are happier with something that looks like a cell phone.
If it's a last-last-ditch-don't even have a pen to stab with weapon, why not chamber it in something like .357 Mag? It's not like you're gonna need to hang on to it and keep shooting, so what does it matter if it flys over your shoulder when it goes off? Because it's not really a last-ditch weapon, it's just a toy and everybody knows it.
I think for a flimsy toy .22, one of those die-cast zinc SAA types for a third the price would be a better option.
