I wanted to buy the Clarisonic mia brush to help clear up my acne and scars. But, decided to buy this as this doesn't require any replacement brush every 3 months, I thought this will be a good investment. I give it 3 stars because it really made my face extremely soft, and the battery life is really long, plus maintenance is very easy for this tool, also it did not flare up my acne, so it's suitable for sensitive skin. But, it really didn't help my acne at all, I don't feel like it helped remove my make up any better than my hands, I think thats a function of the cleanser I use and my cleanser removed make up just as good as without this, so no added benefit of this brush. For me this price tag is not worth the benefit of just soft face. It didn't visually do anything to my face. I regret buying it and I wish I could get a refund, and wish I bought the Clarisonic mia, that perhaps would have helped exfoliate the skin and clear up my acne. This brush is definitely not an alternative to Clarisonic mia, its just a different product altogether. Clarisonic mia removes dead skin, exfoliate and clean (exactly whats needed for acne and scars); this one only cleans, and my hands with my good cleanser are good enough to do that, I do not need 169 pounds tool for it.
