I have been wanting to get a Clarisonic for some time. After reading a few Amazon reviews, I learned that Amazon (and Overstock) are not authorized retailers for Clarisonic, so you are likely getting a fake product. For the reviewer whose Clarisonic stopped working, you can call Clarisonic and read them the serial number and they will tell you whether it's a genuine or a fake. I would demand a full refund from Overstock. Most of the Amazon ones that weren't working ended up being fake after the purchasers called Clarisonic customer service. Anyways, for close to this Overstock price, and same as the Amazon price, you can get the original product from authorized online retailers, almost all of whom are offering 20-25% off for the holidays, free shipping, and manufacturer warranty. Clarisonic has a long list of authorized retailers on their website.
