I really do love sooo many things in this line and I am guilty of purchasing every single pallette she comes out with. My faves, as others have mentioned, are definitely the corrector, concealer, and gel liners.
Overrated products, IMO, are her mascaras (they do nothing for me) and that Bone eyeshadow that she sticks into almost every pallette ( it looks like I've applied nothing and unfortunately I have tons of the stuff).
