The shape of the brush makes it easy to apply to all of your lashes. Honestly, with the exception of Clinique's Naturally Glossy Mascara and the classic Maybelline Great Lash Mascara with the pink tube and green top, all the cream formulas seem the same to me. They all clump, and they all look really matte when they dry (and boy, do they dry). So, if the consistency of the actual makeup doesn't matter to you much, the brush is definitely worth it. Otherwise, try the two I mentioned above. One is expensive, the other relatively cheap. Good luck!
