beauty blast: they're real push up liner

I was lucky enough to get my hands on Benefit's new addition to the "they're real" collection, 'they're real push up gel liner'. I love Bobbi Brown's gel liner so my first question was how is this going to work in the form of a pen? To be honest it takes a little getting used to and I had to play around with it a little but all in all it's a good product and I like that it's waterproof!
