If you want clear separation this is for you. It makes lashes almost feathery, but it does nothing to thicken or substantially lengthen. It's very subtle, so if you are looking to thicken your lashes you will need a few coats. Also, the wand is pretty flimsy so you need to be pretty careful.
This was great for thickening and lengthening, yet it sucked for separation. The wand was nice and sturdy, but the applicator made the product clump easily. While I needed only one coat, I would have to run though my lashes with a clean tester wand (pick them up for free at Sephora) afterwards in order to de-clump them.

This mascara is TERRIBLE. I know it's one that many people use, so I don't want to light a fire under any haters, but personally, I feel that it's one of the worst choices out there. I found it to be clumpy, a poor consistency, and overall not a good investment. While it's signature lime green and hot pink tube may seem attractive, it just masks a dark, globby mess.CoverGirl LashExact
This was another one of the first mascaras that I tried. It was my favorite mascara for about two years. It did a slightly above-satisfactory job of lengthening, thickening, and separating. I needed about two coats to get the look I wanted. The small tube is very easy to carry around and it the color is just-so-cute!

This is my FAVORITE mascara right now. It's the best for separation and lengthening. I use about two coats to get the perfect thickness. I lovelovelove this because you never get clumps. And the wand is even sturdy enough to give a person with Tourettes a steady hand.
Get out there and bat those flirty lashes!
