I got this in the Book of Shadows IV set, so I gave it a try.

The good: it does hold a curl pretty well, and the packaging is pretty.

The bad: everything else.
Sorry, but this mascara clumps lashes together and does nothing for lengthening or thickening. It is a curl+pigment formula only. The look is lackluster. I'm not big on the brush either, which is a plastic spoon brush with widely spaced bristles/points that seem to lend to the clumping problem.
However, even worse is trying to get this sucker off. I don't use waterproof and I'm not sure if this is waterproof or just if the formula is super glue because that's what it takes to hold the curl. Either way, I had to scrub at my eyelashes with cleanser, then eye makeup remover and then still pick off clumps of mascara - and when I finally thought I had my lashes clean, I put on a new coat of mascara the next morning to discover this stuff was still stuck on them. I lost a few eyelashes from each eye trying to get this gunk off.
The pain in the ass this is to clean off in + the less than stellar results of it = not worth it.

this darkens, and adds length & volume to my short, non existant eyelashes. the formula is not too dry and not too wet, which is perfect for me. my eyelashes pretty much just stick straight out, they're very stubborn. i don't really see a difference with my lashes holding their curl with this mascara. i can't really say this is HG because i find this not unique at all and there are dupes for this. this also has a spoon brush. it doesn't smudge or flake. and it's pretty easy to remove. continued >>

I've been on a mascara-testing binge lately, searching for a new holy grail mascara. I got a sample tube of this, and I'm loving it!
The brush works amazingly. I'm partial to rubber bristle brushes in the first place, I find that they really do the job of separating my lashes. I can't speak for the 'curling' part of it, as I never curl my lashes, however it does do an amazing job of lengthening my lashes and making them look gorgeous. I have naturally long, thick lashes, so finding something that doesn't make them clump into a stickly mess is an automatic win.
The only thing I'm not a fan of is the curved wand. I've just never really liked any curved mascara wands I've tried. However, it's not a deal-breaker!
Also removing this mascara is a breeze. It isn't waterproof, so it doesn't pull out half my lashes when I'm ready to remove my makeup!
This one is definitely in the 'may re-purchase' running if I don't find anything better!

The BEST mascara I have ever used in my life. Separates, thickens, lasts all day, fuller and longer lashes, curls, but BEST OF ALL, DOES NOT DRY OUT ON MY FACE..EVER. I love it!

This gives a VERY natural look. Almost does not show up. Not worth the price at all.

I love this mascara!!! I have been on a mission to find a mascara that gives me fullness as well as separation AND doesn't turn gray after a few hours of wear. This one delivers on all accounts and it really does curl my lashes. No need for a curler anymore. I wasn't sure I would like the wand as I'm not usually a huge fan of the plastic applicator type but this one was different and really caught each individual lash. The plus side was it also stayed a very true black color on me. I will definitely re-purchase this product.

Love this Mascara. It's the best lengthening mascara I've tried so far. Even better than "They're Real" by BeneFit.

I've never had my Eye Lashes look this long. it really coats each lash all the way to the end.

Note, if you want volume, do a volumizing Mascara 1st.

Mascaras that do both aren't ever as good as using 2 different mascaras for each.

To be clear: Use one mascara for volume and another for length. For some reason they havent found a way to mix the formulas and get the same effect as using 2 seperate mascaras.

I have to say I have tried the Big Fatty, and Lush lash by UB I really liked this one but, it didn 't do anything like make me go WOW it was just there it is ok would I buy it again maybe not Love Max Factor 2000 calarie thank god for ebay

I got this in the Sephora mascara box set so it's just a trial size. The things I love are the very black colour, the fact that it holds a curl, and the perfect-for-my-eye curved wand. The dealbreaker for me is the fact that it provides zero thickening or definition, both of which I want in a mascara. Makes my lashes look sparse and spidery. Boooo!

My fave mascara of all time is the Benefit They're Real mascara, but I am running out of my tube of that and don't know when I can repurchase. So I have 3 samples of this Urban Decay Supercurl mascara in my stash that i thought I would try. So far i am really loving this mascara..it doesn't smudge too bad, it gives my lashes the same look that They're Real does, it's super black, and does help to keep my lashes curled. i really like it. The only thing I wish is that the wand was more like the They're Real wand. The wand on this mascara is curved and I always have a hard time with curved wands...I am going to use my samples of this until I can get another They're Real..
Update; I have figured out how to use the wand on this mascara and now I LOVE it!! Good thing I have two more sample ones to get thru, then I have 2 b/u's of the They're Real, so I'm good *\o/*
