It works!
This actually worked!  I am very fond of certain brushes that I use.  I can use up to 5 different shadows at once for my desired affect so it is super helpful when I want to use my favorite brush for one application of several colors.  This product allows me to do this.  I still need to do a deep cleaning of my brushes but I don't have to do so everyday like I did before.  i have used the darkest matte black shadows and then used light colors to blend and never have had a problem with transferring colors.  It's super convenient!  I will say that it does not work quite as well for wet applications, but it still works good enough.  I will definitely purchase again!
