agreed with the 15-pan-ers. i'm working on my 7th 15 pan, and honestly, i couldn't deal with having quads, for the volume of shadows i own. the 15 pans are sturdier (at least in my mind), take up less space, and i like how its easier to color code them, versus having to dig through 39329 quads. i have little colored star stickers in the bottom right corner of all my 15 pans, so i know what color scheme is in what palette. i do my makeup in my room, and have plush carpet, so i've never had a breakage problem, although i could see how it would be an issue. i do own a couple empty quads, if i want to pop out a few pans, and throw in my makeup bag for a night out. i de-quadded several of my pre-made quads, and regret it now..oh well, you learn.
