More than the formula itself which is only so-so, it's the brush I love. This mascara alone doesn't give me enough volume, so I usually use another mascara (ie: Maybelline Great Lash) and then use the Clump Crusher brush to smooth out any clumps. I wouldn't use this mascara alone, but the brush is very handy, and for that reason alone I will always have it in my make-up bag.

did not make a difference in my opinion, my lashes did not look fuller or longuer

This mascara IS a great separating mascara however, it gives minimal length and no volume at all. It's not the worst mascara out there but not the best for me at least.

Great every day mascara with ease of use in a larger wand. Easy to apply to both upper and lower lashes with the curved applicator making it easy to get to the small lashes. I upgraded to this one as i heard its clump-free, non smudging or flaking and outlasts. I do find the applicator a bit slippery to handle with dry hands, so i may consider putting an elastic around it just to be safe. Overall, a good choice for me after upgrading from Maybelline Big Eyes dual wand as I found the small brush not very effective for small lashes. great product/

This covergirl mascara is good but it's not my favorite. Instead of it saying clump crusher it should say clump creator.

This is my favorite mascara at the moment! I have short lashes and this product seems to give them some volume and length! Love the curved wand, separates my lashes perfectly. No clumping which is amazing.

I really like this mascara! I find that it makes my lashes are longer, lasts all day and I'm not allergic to it!
The one thing I have to say though is that the brush sometimes hurts my lashes. Probably because the the brush is so defined! I love that this mascara doesn't clump either!
Over all a good mascara for the price!!

I like how the wand is curved to fit under your eyelashes just right. This mascara is great for getting rid of clumps, but I did find that I would need to use a little more of the mascara to get the right amount I wanted. It is a great mascara for those who want a quick, clump-free look!

I love the curved shape of the wand. I have short lashes, and the wand makes getting all of my lashes a little easier. The mascara stays on all day, but can be a little difficult to get off.

LOVE THIS MASCARA! Very buildable! Separates my lashes very nicely for a fluttery-not clumpy look.
