To start off, I am a makeup snob. There are very few drugstore products I will buy because I'm very fussy, especially about eyeshadow. I like good blendability and high pigment density, neither of which are usually available in a drugstore line.
Wet & Wild is suprisingly the exception. I find there shadows to be better than some high end brands (I'm looking at you Stila), and comparable to MAC as far as texture and pigment.
I travel a lot, so I wanted one eyeshadow pallate that could take me from day to night. I'm an NW15 (actually 10) with pink skin, and this is perfect. I can either do a nice natural eye, or a smoky purple or smoky gun metal, just by changing my liner.
So worth the $5.
