I love my Clarisonic brush. I've noticed a huge difference in the way my skin feels and looks since using it. The best thing about it is you can buy the brush heads you need for your particular skin. It's definitely worth every penny.
I like it and find it to be effective however I've used cheaper products that are similar and received very similar results. What I did like was the brush options. I was able to get a softer one for my sensitive skin.
