For years, I have sworn that Great Lash was the best mascara on the market, til I tried this one. This is by far the best mascara I have ever used. From the unique squeeze tube packaging, to the perfectly spaced bristled brush, this mascara does it all. It lengthens my lashes like no other. No clumping or smudging. It even adds a bit of curl (altho for me, an eyelash curler is still a necessity). Easy to apply, it washes off easily, but is pretty water-proof. I will definitely be adding this product to makeup bag on a continual basis.
