When i first got this brush, i loved it for the first two weeks. But it became stiff. The bristles became stiff. I don't know what is going on, but it definately feels harder than when i furst used it. It was so soft and i loved the first few times i used it. I'm still using it because i paid money for it, but i use it on speed one, so it won't hurt my face. I use the radiance cleanser with it. But honestly, i haven't seen much difference. My face looks the same. I don't see much radiance. I'm not going to buy it again. I'm thinking to get the cashmere one since the other ones tend to get stiff after a few usages. I do hope Clarisonic works on that because i love Clarisonic and would to keep using its products.
