Regular & Waterproof Mascara Duo is rated 3.4554 out of 5 by 661.
Rated 5 out of 5 by from Good for me! I was skeptical simply because of the condition others received this mascara, however mine came in great condition. The black/brown is a bit darker than it appears however. (That seems to be an issue with several elf items and their online photos however.) At $.80, I'm thrilled!Goes on as well as pricier mascaras I usually find. My only wish is that elf would give us plain brown shades - some of us are of the fair skin and blonde lashes/eyebrows group ;)

Rated 1 out of 5 by from Terrible. I bought this product and came in today. I opened it up and it was so hard to pull out. Finally, it pulled out and the brush is messed up and its all so dry. I normally love their products but I'm sure this was just a bad one.  Since I think it was just a manufacturing issue, I'll order a new one.

Rated 5 out of 5 by from I was surprised by how much I like this I received this for free with a promo code and didn't have high hopes. I was impressed! I've only used the regular side and I haven't tested how waterproof it actually is, but I like this a lot! I use it to lengthen my lashes (it isn't very good for volumizing though) and then apply a volumizing mascara on top. Overall, I love it and I would totally repurchase for such an amazing price. It doesn't seem to weigh my lashes down like a lot of mascaras do. The wand is also an excellent size for my small eyes. The packaging is awesome for travel or to throw in your purse!

Rated 5 out of 5 by from Amazing product and price This mascara duo is fabulous. I have used a lot of pricey mascaras from the shopping networks and I do believe this product is as good or even better than some.

Rated 1 out of 5 by from Dried out in a few days Maybe I got a bad one, or maybe the formula is too dry to begin with. I bought mine at Target, so maybe it was old, but it never applied well, and was completely dried up after a few uses. Elf makes plenty of good mascaras, so skip this one. I recommend the waterproof Studio one.

Rated 5 out of 5 by from I was skeptical at first to try this and I'm so happy I did. For $1 it's fantastic! I have the worst luck with mascara because I have pretty short lashes and it takes a while to give them the proper drama I want. My eyelashes lengthened and volumized within a decent amount of coats. Really regret not trying this mascara and stocking up when they had it at my local dollar store :(  but glad I know where to find it now!

Rated 2 out of 5 by from Too Clumpy Sorry elf, giving a bad review. It's too clumpy and it's very hard to get off. I wouldn't recommend this to people. I would rather use other cheap mascara like wet&wild.

Rated 1 out of 5 by from i bought this a few weeks ago, and it is terrible. the regular side is okay, but the waterproof runs down your face and its super hard to get off.

Rated 3 out of 5 by from Clumpy This wears great but it is VERY clumpy when it comes out of the tube so it takes a lot of after brushing with a spolie brush.

Rated 5 out of 5 by from Great wear, Doesn't burn eyes First time wearing any mascara of any kind. I am very happy with it. I don't feel like I'm wearing it, it looks great, doesn't flake, and doesn't have any negative effects such as burning.

Rated 4 out of 5 by from Pretty Good Overall For a dollar - amazing quality! It dried quickly and sealed my curl (I use an eyelash curler) for a few hours more than my other mascaras did. It adds a substantial amount of length and volume to my lashes. I love how it doesn't smudge on my eye lids. The water proof one goes on much easier than the regular one, which tends to clump up. But it's very difficult to take off! I stood at the mirror for nearly half an hour with makeup removing wipes, paper towels, and water (I'm an idiot) to get it off. It'll probably run out in a month because I use it everyday, but it's only one dollar and they sell it at my local grocery store! :) Overall - I like it.

Rated 4 out of 5 by from Nice Got this couple days ago. Never had elf mascara. Used before only loreal and Lancôme. It's super cheap, apply easy and nice (my eyelashes look much better than when I use Lancôme mascara). Doesn't last long. After an hour or two started falling

Rated 5 out of 5 by from My go-to mascara now!! This mascara duo is so amazing. I have tried many HSN and QVC mascaras, and while they are excellent...they are pricey. I am truly stunned by this product from ELF. It stands up to any of those other mascaras. I never want to run out.

Rated 4 out of 5 by from love the duo I have bought both the black and the brown, love the fact that one is waterproof and one is regular so I can use one on the upper eyelashes and the waterproof on the bottom since my bottom lashes are a bit long.The only thing is the waterproof drys out a bit, but with the cost being so low I can more for the same price of one of the other brands.

Rated 4 out of 5 by from Doesn't smear Product Feedback on 3 of your mascaras:#1 - Regular and Waterproof Mascara Duo- this was the best mascara! This is what made me buy the other two mascaras listed below! The regular stayed on all day without smudging AT ALL!!! I was so happy! It applies nicely in one coat.But due to the small size, it only lasted 3-4 weeks! I tried to find the larger version of the REGULAR, but it's not listed on your website or anywhere else. I wish it lasted longer than a month, I'd buy more! Again, I thought your other mascaras would be as good, but they smear really badly. And, I don't want to wear waterproof mascara on a daily basis. I would buy this mascara again and again if it came in a larger size.#2 - I'm seriously disappointed in Mineral Volumizing Mascara: it smears within 30 minutes, doesn't apply well (takes multiple coats), and I was wiping mascara from my upper and lower lids all day. Within 1 hour, there was no mascara on the tips of my lashes (it was on skin :-(( Raccoon eyes all day!#2- Volume Plumping Mascara - this stays on a little better, but still smudges under my eyes after an hour, but not as badly as the Volumizing. Also a disappointing product.Gina McMurray

Rated 5 out of 5 by from Makeup Artist Fav! All I can say is wow. I work at M.A.C makeup and often compare our products to those from the drugstore. For a buck, this mascara is perfect! It stayed on all day and didn't smudge. This is a perfect product!

Rated 1 out of 5 by from Didn't last long... Good color, not so great formula. It ran out in a week compared to my Maybelline products taking more than three months to run out. It was flaky and irritated my eyes also.

Rated 1 out of 5 by from i dont know whether is it just mine but mine was so clumpy and dewy and dry. i literally cant put it on my eyelashes

Rated 1 out of 5 by from Not very good! While almost all of ELF products are great, it is not so with their mascaras! I found this dry and clumpy. It didn't do much for me. It lifter my eyelashes at first but minutes later it looked like I was wearing nothing. It is waterproof though! So if you're looking for barely there and waterproof, give it a try.

Rated 1 out of 5 by from next maybe it was just mine, but I found it dry and clumpy. I did not like it at all. It was hard to remove, but it is to be expected and was completely dry in the tube in less then a month. I have never had a mascara do that before or since.

Rated 5 out of 5 by from Worth Buying I bought this today and tried it on to see how it looked, and it went on great! It looks great on me as well!~ I tried the regular side which hasn't clump,flaked or irritated my eye at all! <3 New Fave Mascara~ Only thing that I think is a con is color selection!~ I like brown mascara and other colors! But I can live with wearing black for now

Rated 3 out of 5 by from Great for Beginners When I was first starting out with makeup I bought tho and LOVED IT! Also, it's great for beginners, because you can experiment with both regular and waterproof without having I buy 2 seperate mascaras. Another bonus is it come in 2 basic, common colors.

Rated 4 out of 5 by from Pretty Good I bought this for the wateproof side for detassling and while its waterproof neither side are that great no volume and only slight lengthening properties plus it broke but for 1 buck still better then expected I have it in black-brown which is darker in person but it's good when I do mens makeup on my guy friends

Rated 4 out of 5 by from WOW! Wow! I got this product in the brown shade and LOVE the waterproof side. The normal isn't fantastic, but you can't beat the price!

Rated 3 out of 5 by from I think it's ok I mean I don't like the way the regular mascara clumps up.But I do like waterproof it is long lasting and it does not clump as much as the regular mascara does
