I also received this in a gwp when I purchased some Clinique products. I was excited to try this as I had been using an eye lash serum and they were looking good, and I thought they would look even better with a great mascara.
I was so dissapointed with this. I didnt get any more volume or length and the colour didnt have much of an impact either. It seemed to dry out during the day and started falling off my lashes. I am happy I didnt "pay"for this mascara.
I received a mini version of this as part of a Clinique GWP. The brush applicator looked promising, it is of the natural bristle variety and looks like it would give you lots of volume. Unfortunately this did nothing for my lashes, gave me no volume, only a little length and didn't hold a curl very well. I also found that it flaked off my lashes somewhat throughout the day. After a couple of uses I have thrown this one out- lifes too short for a bad mascara!
This one is hugely popular but unfortunately did not work for my lashes so wouldn't personally recommend it.
