I love this as a kit. It gives you everything you need to keep your brushes clean and lasting as long as possible. The best part of this kit is the cup with the rough bottom that you can scrub your brushes against. It works amazingly well. The other parts of the kit are great but I feel like you could replace them easily with your own substitutes for much cheaper. However, the rough bottomed cup is very unique in my opinion and makes it worth getting the kit one time and then replacing the other things as necessary with cheaper options. I also have a complaint against the brush shampoo not being the greatest cleanser. It takes several scrubbings and a lot of product to clean foundation brushes, but if you go back and then also clean them with a regular face cleanser, it still gets more gross stuff out. So I definitely wouldn't repurchase a full size of the brush shampoo.
