I purchased this from the Suzykirei store. I used to wash my brushes with a mild detergent and dry them in the shade whenever I felt like it after using up my CLINIQUE brush cleaner a long time ago, but I wanted to try it again after a long time, so I chose this highly rated product. Unlike CLINIQUE's spray-on type, this one is a direct application type. It dispenses a larger amount of liquid at a time. It removes foundation and eyeshadow well. It's hard to say how cost-effective it is, as I haven't used it all up yet. I'll update once I've used it all up.
