I've been using it for a little while now, and as a mascara junkie, I must say this is unlike any other mascara I've ever used.
The Good: This mascara gives me amazing length, volume, and curl. My favourite thing about it is how easy it is to layer and build to create more and more length (length is a big deal for me). The gel formula is unlike anything I've ever used, ever. It stays in place, dries well, and adds to the end of each lash. This summer I tested this mascara in the pool, the rain, and the humidity and it didn't budge (a few flakes here and there, but it never rubbed off and was never runny). Also, the name and packaging for this product are both irresistibly adorable.
The Bad: The company claims that this mascara is "water resistant" but it's more like super glue. It's incredibly difficult to get off. I've used about 4 different eye makeup removers to try and remove this stuff at bedtime and although it's possible, it hurts and takes a lot of effort. I've actually resorted to wearing another more washable mascara underneath this mascara to make it easier to remove at night. Beyond the removal, I have no complaints whatsoever.
Overall: Beyond my difficulties removing this mascara, I have no complaints. This stuff does wonders for my lashes and I actually consider it to be the best product I've ever received from a monthly subscription box. I would highly recommend this mascara.
