I was so excited to try this mascara after a couple of work colleagues recommended it me but I found that it didn't really live up to the hype.
The pros for me are that it does add volume and lengthen the lashes leaving them looking quite good when you first apply it. However, the cons really outweigh any of those pros for me. The brush is quite large, difficult to use, and it clumps easily. The mascara smudges and requires an under eye finger sweep periodically throughout the day, which is far too high maintenance for me! Plus it is super expensive compared to its equivalents. I also found removing it quite difficult with a lot of product left at the base of my lashes after washing my face (which doesn't happen with other mascaras). Wouldn't recommend.
I've tried both the sample size and the full size of this as sometimes the formula acts differently but unfortunately this mascara is just not for me. It coated my lashes fine but nothing that "wowed" me. The issue is that this mascara flakes really badly on me and leaves black spots on my cheeks. I have tried powdering under my eyes in case it was the oils on my skin breaking down the mascara but unfortunately it made no difference. My sister found the same thing happening to her when she has tried the sample size.
I fully allow for the fact that this is personal preference though, as I then gifted my mascara tubes to my niece and she loved them.
