You could go through the bothersome, tricky process of shaving your head with a tradition razor … or you could just use a shaving helmet and get it done in 20 seconds. Invented by a Brooklyn dude named Boris, the shaving helmet features blades powered by two servo motors, a shaving cream injection system, and LED indicators that show when the cycle is over.

If it sounds a bit dangerous, well, don’t worry. The helmet was tested on an actual live human man. This video shows him being shaved without even a nick, let alone gruesome injuries. Sweet! But for those of us who don’t shave our heads, it would be awesome if Boris could make an even-more terrifying shaving mask.
