This is one of my favourite MAC products. I use this product every single day, for all my makeup application. I use this product not only for highlight on the eye, but it works really well as a base for your eyeshadows to adhere to. It's creamy, smooth, and foolproof to apply! In order to get the most out of this product I apply to clean fresh eyelids, and once it sets I apply a nude powder eyeshadow over top (I use Urban Decay FOXY, or W.O.S) to increase its staying power. I have quite oily eyelids and since I started using this product, my product no longer migrates or creases.
