I bought a Clarisonic Mia during the Sephora F&F sale. I love it, but I don't think it's something I necessarily need. Just like my electronic toothbrush - great to have, but I wouldn't die without it. If you can get one on sale, I'd recommend buying one. I used to slack sometimes on washing my face if I was super tired, and since I bought my Clarisonic, I haven't missed a night b/c it's so easy to use.

I have had one for about 6 months now and love it. I would highly recommend it. It is so easy to use and the results are amazing. I have the pink one. I don't recall what make it is but it is not the mia its the bigger one. I got it at Sephora.
