Great product. I have oily lids and I need a waterproof eyeliner or I get raccoon eyes. This has a very nice, thin brush. The formula does dry a bit shiny, but I don't have an issue with that. It does take a bit of time to dry. It does last all day. My eyeshadow will be creased, but my eyeliner looks perfect. I find a bit of rubbing with water will take this right off.
