I've got Midnight Cowboy Rides Again, which is, if you can believe this, a more glittery version of Midnight Cowboy. I've also got a couple Deluxe shadows and Mildew from their regular shadow line. Mildew is beautiful, soft, pigmented, and easily blended.
The Deluxe shadows are great, even more pigment intensive, and also easy to blend.
Midnight Cowboy Rides Again is an absolute nightmare. Fallout is pretty much unavoidable, if you try and blend it you just spread glitter further down your face, and pigmentation is just more glitter. I pat it on with a little Visine on the brush, and that limits the fallout a bit, but it's definitely still there. Really though, I've never met a glitter heavy eyeshadow that didn't do all of the above. If I want to have that glitter look on my lids, I apply UD's Heavy Metal eye gel on top of my shadow, which stays put and doesn't muss your eyeshadow up so long as you pat it very gently on top.
I really don't know how it's a top seller either, considering they've got lots of lovely shades that don't have the same issues. I don't hate Midnight Cowboy Rides Again, if I'm going to be at a place where glittery cheeks won't be noticed I rather like it, but it's very hard to work with compared to their other shades.
