I bought the smaller version of this mascara to try it but the brush was identical to the full size version. I found it very effective and did not clump. I found even more effective if you applied with the long bristles and then went back with the short sided bristles. This allowed for a better curl and also spreads out your lashes more.

I guess mascara is a very personal item. You either like it or you don't. For me, this is a no go. It doesn't make my lashes look better then what I'm currently using.

I've become quite the fan of benefit mascaras recently and I'm really digging Roller Lash. It separates and lengthens lashes incredibly well. I find one coat is enough to lengthen, curl and darken my lashes. It doesn't give a ton of volume which is nice when you want a fun and flirty look.

I have little to no lashes and they seem to sit straight out from my eyes! This mascara does not clump and it role and lengthens my lashes perfectly! It is a little pricy! I got mine from a beauty subscription box as a deluxe sample and as I really do love it! It can cost up to around $30 a tube. But if you are in desperate need of lashes and don't mind the price it also lasts me all day and does not melt into my under eyes which I really loved as well!

I’ve never been loyal to one mascara… until now. This product actually lives up to its promises and really does curl your lashes unlike other mascaras - and trust me I’ve tried a lot of them. The thing I especially liked about this mascara was that I don’t need to use as much of the product because it actually works. Just took me a few tries to get the hang of it.

I love this mascara! In my opinion, this is worth the money for the quality. I usually don't notice that much of a difference between drugstore vs. high end mascara but this one is by far better! It keeps your lashes curled all day, really lengthens them and I don't find it flakes off at all. Out of all high end mascaras I think this will be the only one I would actually purchase full size!

This is a good, solid mascara with a very nice wand. I like the way the sample size wand fits in my hand and works around my lashes. I have few problems with smudging during application thanks to the tiny plastic bristles.

It's a little expensive for the final effect, but I'm using this one up for sure.

I received a couple of samples of Benefit Roller Lash Mascara in the past year and while I do like it, the price to purchase them at full price seems high to me. While at first the product applies evenly, it does get clumpy quite quickly. The unique roller lash applicator is very effective though, and I noticed a definite change in the fullness and curl of my eyelashes. Perhaps if I cleaned the applicator after every use it would reduce clumping, but ain't nobody got time for that.

I bought this on a whim and ended up loving it. If you twirl the brush as you apply the mascara, you get ZERO clumps. Sometimes, though, if looks great, other times my eyes end up very uneven looking and I have to use another brand to plump them up. I would not say they are particularly curly after use.

I love benefit mascaras and thought that my holy grail was the They're Real mascara, but this is better and the wand makes lashes more lengthening than They're Real. This does not smudge on me and holds my curl until I remove it.

I curl my lashes before and after application because I have stubborn lashes in my outer corner that will get weighed down by this mascara.
