This is the worst mascara I have ever tried. It looks okay when you first put it on, but after several hours it clumps badly. It definitely doesn't last even overnight and certainly doesn't last the three days they claim. The problem is, it comes off when you don't want it to, and doesn't come off when you do: I had to really scrub to get it off, and it irritated my eyes terribly. I don't recommend this at all. It's not even a good mascara for one day.
