AWESOME!
Grew my lashes and works amazing, I cannot wear mascara without this now. It really helps to not have mascara get really hard on your lashes and the mascara comes off easy, acts as a protecting layer. Lashes don't break when taking mascara off. Also enhances the mascara.

This product works pretty well, but it is a pain to use. If I can get a nice, even application, it adds lots of volume and makes my mascara last a long time. It also really helps curl hold well. But it dispenses in a way that makes lashes look funky and clumpy, and it leaves lashes very sticky once it is applied, so it makes mascara more challenging to apply. So, after curling I need to apply it, then comb out my lashes to un-clump them (which results in lots of wasted product stuck to my comb), then apply mascara *very carefully* so as to avoid re-clumping them, then wash my lash comb and wait for everything to dry out. This makes the product too much of a hassle for frequent use...I only turn to it on special occasions, and to me it isn't worth keeping around just for that.

Ok, but Estee Lauder is way better. The brush is cheap, but the product lasts a long time. If you do not put your mascara on as soon as it dries, it will ball/flake off. I really like the clear tube so I can see how much product is in the tube.

good.

I recently discovered the magic of eyelash primers after purchasing a cheap drugstore mascara/primer combo (Jane) and falling in love with the primer. I never knew it could make my lashes so much thicker and fuller. It enhances any mascara significantly.
So after learning that primers are not sold at drug stores I ventured off to Ulta to find a brand that does. An associate was going to show me a Tarte primer, but unfortunately they were all out, so she mentioned Benefit but I saw this before we got to that section so I picked this up instead. I've also always wanted to try Smashbox but I never came across any product I really wanted/needed.
I will start with the pros&cons and go from there.

Pros:
-the packaging is clear so you can see how much product is in
-packaging is nice in general and reminds me of MAC products, it's also plastic so it won't break if dropped
-lengthens lashes a little bit

Cons:
-it's goopy and clumpy, so you have to really work with it and put time and effort into making sure lashes are separated
-it's pricey
-does not thicken as well as I had hoped
-it's wet and runny so it does NOT hold curl
-the wand is just awful... this needs to be redesigned stat. It is one of those spiral wands where the bristles are not distributed evenly. Whoever thought this was good for lashes is an idiot - it makes lashes stick together because they get between the gaps instead of being combed out evenly.

I am really disappointed with the wand and will try to replace it though I am not sure how easy it will be to find one that will screw on correctly. I also always curl my lashes prior to applying mascara because it looks sooo much better and makes my eyes look wider/more awake. This product straightens them almost completely :( which sucks because I expected it to hold curl based on previous reviews.

After comparing this primer ($17/ea) to my other Jane mascara/primer combo (about $4/ea) I am definitely baffled. The Jane primer is the one that inspired me to go out and buy a big tube of more expensive "better" stuff. Seeing that I can purchase 4 of the Jane primers for the price of one of these I think I will reconsider next time... or maybe I'll try a different brand.
If I could I would give this a 2.5 lippies. continued >>

This is not a good eyelash primer. The texture is too thin and takes a very long time to dry. Therefore it is also no weightless enough like I have experienced with other (drugstore) primers which means it will not hold a curl. It does not extend as well either. Volume wise its ok but there are some drugstore primers that exceed this one by far. Packaging is the only thing that is really cool about this one: it is clear so you can see how much product is left. Nevertheless, you need to toss it after 3 months anyway, just like regular mascara - so this does not make up for the overall bad texture of this product.

Don't bother. Made absolutely no impact on my lashes regardless of how I applied it. Just buy better mascara.

I really like this lash primer. I didn't think I needed one until I just bought it on a whim. I used it a few times a knew it made such a difference. I made my mascaras not as flakey. It held up my curl a lot better and it gave a bit more volume. I thought I was just making myself believe it but it was true. I put on my mascara one day without my primer (it was finals week and I was too lazy) and I noticed how my lashes weren't as thick and they were straight within a few hours. I've had it for a few months and I've used it almost every time I use mascara. Sometimes I add enough to get the product on and to see white on my lashes and sometimes I don't see product on my lashes but know its there because I can see a difference in my lashes. But either way, it has helped with my lashes and mascara to look thicker and fuller. Will definitely repurchase despite the price, maybe I'll buy again when there's a sale. Overall, I would recommend this. Lash primer makes a huge difference.

I love this lash primer. I didn't know about it until I got a sample one time & decided to try it. It really does make your lashes so much thicker & longer when you put on mascara right afterwards. I need all the help I can get with lashes & I will not put on mascara without lash primer. continued >>

I had a love and hate relationship with this primer depending on which mascara I combined it with. The one major thing I did love about this primer is how well it held up my curl! I am a huge drugstore mascara user due to the fact that I have to repurchase a new one every 3-4 months. I have some high end mascaras from kits as well, but my drugstore ones are better for my type of lashes. The main thing I noticed with this primer is it clumps... A LOT! It does not do so well with volumizing formulas and tends to clump my lashes together with the primer underneath. This primer does work best with fiber tube type technology mascaras on top. I used this primer for a month and decided to return it. I wanted a primer that would work well with all my different mascaras. I don't wear fiber tube type technology mascara that often as they tend to flake and it gets stuck in my contacts.

The tube is see through which is a plus and can see how much you have left. I don't like the wand stopper in the tube, it is very odd and leaves a ton of primer residue on the opening rim which wastes a lot of products.
