Review (5/5): Exactly as advertised~!
I totally recommend this. It gets like 95% of the color off the brush if you decide to use the same brush for different colors. It's reusable as well, which is very convenient and means I don't have to keep replacing the pad. :) All you have to do is pop it out and use the other side! It's also very easy to clean. I clean this out when I'm cleaning my brushes and leave them to dry overnight. I use this daily as well.
If you're looking for a good quality color switch product, this is definitely it.
