This is the second time I have purchased the Clarisonic Mia on Groupon . When the first one broke, I chalked it up to just being a defective item and bad luck. But this second one also gave out after just 15 months. It will not take a charge, and just died. This is generally a great item, but you should not need to purchase a new one every year. I think Groupon is selling defective items and in the future I will purchase directly from Clarisonic.
