I never NEVER use another mascara. I have tried expensive products with ridiculous catipillar brushes that clump and flake and really upset me. Great Lash , however, never clumps up on me and never flakes off all over my face. It's a very seductive shade of black. On top of it's quality, I also have to add that one tube lasts a decent amount of time. Since I really don't have to reapply it, I don't use it up very quickly. It's a product I trust and that is saying a lot. I am very picky with my makeup. It doesn't matter what liner I use either, this product simply can't go wrong!
