How?!? – Real Razor (Prank) Review

I don’t usually write reviews, but I have to for this gem. I’m genuinely curious how this thing works?!?! You turn it on and it doesn’t do the actual clipping sound until you put it on actual hair. I’ve ran it all over myself and my surroundings and it ONLY changes when I put it on my hair. I’m so confused and amazed.
