I too like the pre/post (I have the sensitive variety), like others have said I'm not sure how much it does as a pre shave except it feels nice. As a post shave it cools nicely and feels like it moisturizes fairly well. I have an oily complexion so pre shave oils are usually a bad idea for me. Something you just have to try I think, I do use RazoRock pre shave soap and think it helps my overall shave and would recommend it over the others.
