I've used this eye primer by the Saem for a couple of weeks now and it's already almost empty - that's because I've used it almost every time I've put on make up. I really like it because it absolutely does what it claimes. It makes my eye make up looks last a lot longer. Also it's not drying at all and it's not really sticky or overly siliconey, just the right amount of stickiness so the eye shadow clings to it nicely. I've already repurchased it and will continue to use it.
