Hello,
We just processed your replacement for the unit. The order confirmation number is SO0474969. So you will be receiving a brand new Mia unit via UPS to the address you provided below within 5-7 business days. It will arrive in an ordinary box (the unit is brand new - not refurbished) with its own 2 year warranty. Since your malfunctioning unit is not in the US, you can discard or recycle the unit on your end upon receiving the replacement. Thank you very much for contacting Clarisonic and have a great day.
