When they had the friends & family deal last year, I invested in all the UD shadows I didn't have already, because I love them so much. They are vibrant, last all day and blend like butter. Yes, you get lots of fallout with the glittery shades. I just use them with a little Fix + and no more fallout! I am in love with these, much more so than MAC shadows. With MAC, I find myself having to reapply towards the end of the day, or getting frustrated because many of the colors which look bright in the pan don't "pop" without a light base. With UD, the colors are true to what you see in the pan with any base you use.
