This kit is a neat idea. It includes a cup for washing brushes, for drying (and storing) brushes, an OK brush cleanser, and some reusable brush guards.
The novelty of this kit is the washing cup. Inside the cup, the bottom is covered in small nubs. The idea being that as you swish your brush over and through the nubs, the bristles receive more cleanser and soap, thus a *cleaner* brush.
The cleanser does an average job of removing makeup and skin gunk from the brushes. A bit of cleanser can be poured into the blue cup with a splash of water and swirling the brush around the bottom of the cup will begin the cleaning process. Its is IMHO that rinsing with tap water is the only reasonable way to ensure the brush is clean of makeup goo as well as clean of cleanser.
If you are diligent about cosmetic brush care already, this may not be a great kit to quickly clean your brushes. If you *forget* to clean the brushes regularly and they are pretty gross, this kit might be a jumping off point.
Here is why. A brush used for mineral powder foundation can be considerably dirtier than it appears. With a few stirs and swishes, the water quickly will become dirty. Dump it out - add more cleanser (?) - swish and repeat...
Maybe there is still *enough* cleanser on the brush so you can just add more water to the cup. For my brushes, which can become neglected, I would have to empty and refill three or more times and still feel the need to rinse with plain water.
Another irksome quality --- the height of the cup. It is great when using it as a drying/storage cup but I do not like to completely submerge the bristle head into the water for prolonged washing. I did not find it useful for kabuki brushes (too tall) or for large, full powder brushes (to small inside cup). I think I will return to my previous method which is the same idea but works better for me.
I purchased a *rubber-y* soap dish that has large nubs/bumps on the bottom to left a bar of soap out of the water. A bit of brush cleanser in my palm, swirl bristles in palm, a bit of water in soap dish and swipe the bristles back and forth. If it needs additionally rinsing, I can hold the soap dish in one hand, the brush in the other and use running tap water to quickly finish the job.
The brush guards are cool. They are especially nice for rushes that dry weird no matter how hard you try and reshape them. I will purchase more of the brush guards separately.
