It does remove hair.
I've looked at these for a long time and wondered exactly how they work. The spring thing does a pretty good job of capturing and holding on to multiple hairs, and then when you lift the device away from your skin the hairs are plucked. It's not magic, and it would be quite difficult to remove either an individual hair or extremely large areas of hair with it, but if you're just feeling a bit fuzzy it does the job. The sensation is about what you'd expect, pretty similar to an epilator. Not perfect, but more effective than I was expecting.
