Usually I'm a big fan of shadow sticks. They're time saving, a few swipes, blot with a finger and you're done. The trick is finding one that has staying power. Something about the shadow sticks seems to make them prone to fading and creasing, within a few hours you were better off without any shadow at all. It looks awful.
I don't usually even mention the shadow sticks that don't work out on the blog, but I keep getting asked about this one, so I bought one to try out. Initially I was impressed, the color really is very pretty! There's great shimmer and depth to the color. But despite trying out this shadow stick with (and without) many different eye primers, I can't seem to get it to stick around longer than an hour or so. I've blended it with my finger and with brushes, that doesn't seem to make a difference either.
I did read a few reviews on-line where people were using the shadow stick as a base for shadows. When used that way it can add some very pretty depth and intensity to powder shadows, but the staying power still isn't great. I get about 4 or 5 hours of wear this way, much less than a normal shadow primer. I would prefer to use an eyeliner in this way, the wear is much better for most given how smudge resistant most eyeliners are, my favorite for this are the Laura Mercier Kohl Eye Pencils.
Although $2 sounds like a steal, I would definitely pass on these shadow sticks.
