This is a FANTASTIC product! It is foolproof to apply if you have the right little angled brush, and even if you are a little shakey your eyeliner still goes on with ease. I was a little hesitant to buy this, but I am sooo happy that I did! The gel formula is quite thick, but it glides on smoothly and I havent noticed any smudging. It lasts all day, unlike other liners, but washes off easily and doesnt irritate the eyes. The colour is fantastic - the black colour is intense, so perfect to create a cat-eye appearance! The little pot is super-cute, but tiny, so I was worried that I would use it up too quickly, however you need such a small amount that it will last for ages. This is a real "must-have" for any make-up bag! Highly recommended!!!
