Love the clarisonic Mia. I had a full size clarisonic for years and the battery died. I did not want to pay for the full size one again and decided to try the Mia. I'm glad I did. It works just as good as the full size clarisonic and the brush head is really not that much smaller. It doesn't provide the timer for different parts of your face and I'm fine with that. It was a good option for me and I have the option of easily taking it when I travel since it has a much smaller charger.
I just recently bought Mia1 Clarisonic each for myself and my hubby. We only use it once a day. So far, all positive both on the units and our experience with the use of the units.
