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 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
