Review (5/5): very nice!
When I first got the MiroPure, I left it to charge overnight and was upset when it didn't turn on the next day. It took me a few moments before I realized you have to hold the button for a few seconds before it switches on. Another click speeds it up etc and holding the button turns it off again. It vibrates rather than spins, which I prefer because the cleansing brushes that spin tend to get that inevitable wisp of my hair escaping my clip and tangled it.
