Review title is Easy to use, but did not produce “clean” results. [SEP] I really wanted to love this product as it has one adapter for all makeup brushes. The instructions were easy to follow and a no brainer. However, I spent over 5 mins trying to clean one brush and the results were less than satisfactory. Did not seem to work well for foundation flat brushes. AND as I was pulling out my makeup brush, the brush handle came apart into two parts. I ended up cleaning my brushes the old way and saved myself time and frustration. I will be returning.
