I got the 4 pack of deep pore cleansing brushes. They were an exact match for my clarisonic mia 2. It fit well. My only complaint is the bristles were as stiff as the clarisonic deep pore brush. I feel they all just a tad more softer which I prefer for them to be a little more dense since its deep pore cleaning. But I will continue to use them especially four for $14. Looking for a cheap alternative or on a budget these will do just fine. Gives you a great cleanse.But I will be going back to Clarisonic for my brushes when they run out.
