I'll personally never buy UD palettes now, though I have considered it in the past. They're just too over priced for what they are. If i'm going to put $54 dollars towards a single (or couple) pieces of makeup, I'd rather it be something from Dior, Chanel, or YSL. I'll stick to my mid range brands for every day basics, they've always worked for me.
I think this brand appeals more to people who are just in to labels, anyway. People have raved about their 24/7 eyeliner pencils for so long, when I was just getting back in to makeup and researching a good eyeliner. But once I started using other eyeliners, I realized how bad they really were.
