Vibrating Mascara - Newest Makeup Technology?

This sounds a little scary to me, but I am willing to try it out. It makes complete sense because one of the application methods for applying mascara is to move your hand back and forth so you spread your eyelashes apart and and get more mascara coverage on your eyelashes. With that being said, instead of having  unsteady and uneven eyelashes from manually moving your hand and doing the motions, the vibrating mascara wand has been invented to save the day. It scares me having something moving that close to my eyeball, but I guess it could be worth getting used to.
