Review (2/5): Arrived broken, would not turn on.
I was so excited to get this, but when I got it, it was broken. I could not get it to work by plugging it in or installing batteries. I was a little disappointed I couldn't exchange it for a new one, and now there are none in stock. I've heard great things about this shaker and for now I'm still stuck shaking my polishes by hand. I'll update this review when/if I get a working shaker.
