I love this mascara! I actually got it for free last year over Black friday when Mac had a Spend X amount and get a free gift. I didn't really need a new mascara but I'm so glad I got it! It's now my favourite mascara.
I find that this mascara lifts and lengethens my lashes. It separates my lashes well and helps create a nice bold look. If you've ever use Better than Sex by Too Faced I find it to be quite similar to that but now quite as clumpy.
The only bad thing about this mascara as since it creates quite a bold look, I find that quite a lot of mascara goes on your lashes so you have to be careful not to blink too hard as it takes a while to dry and leaves marks on your face that you then have to clean up.
Never the less, this is my favourite mascara of all the ones I've owned and I usually save it for special occasions.
