I experienced one of the older versions of this injector at a free vaccinations offered by my college. I'd say it hurt more than the needle, but it was faster. They were also vaccinating a huge line of thousands of students fairly quickly.
After the injection was done it looked like there was a tiny worm sticking out of my arm (where the vaccine was kinda leaking out). Weird!
