I've been using this for about 2 years by now and I haven't found a better primer to date. I tend to wear very dramatic and colourful eyeshadow so creasing is my nightmare. I've tried out MAC's prep&prime and Smashbox's eyelid primer and in comparison they were rubbish if I have to be honest. Neither of them stopped my eyeshadow creasing, but this did the job. A tube lasts me close on 6months so it's not a bad investment at R100.
