I purchased this in August of 2013 and was excited to try it because of the past reviews it has gotten. When I received it, there was no invoice in the box and the Clarisonic box was damaged (which is likely why it was sold on Overstock). I have been using it twice a day and loved what it did for my skin. Three days ago it quit working. Won't even turn on. It is fully charged and I have tried everything. Bottom line: What is being sold on Overstock.com is clearly defective for some reason. I should have known when it said it was not returnable, but I purchased it because it was cheaper than ordering from the manufacturer. Save your hard earned money and purchase direcly from clarisonic.com where they will stand behind their product. Most disappointing purchase I have ever made and will not purchase another thing from Overstock again.
