If you need to smash glass, why not use a rock and slingshot? Isn't that a whole, whole lot cheaper solution? Or a BB gun? Also if a drone comes flying in a room where you're barricaded, it's time to fire the shotgun at it or just throw a pillow at it. If it crashes to the floor, I'm tossing a towel over it. Take out the battery and toss it back out the window. XD
