Hi there, I don't use singles from UD or any of their glittery shadows other than the UD naked franchise palettes. I did have the Alice in wonderland but sold it due to the colors not really being for me. IMO I feel the amount money I spend on full retail price makeup (no pro discount), I shld get exactly what I'm looking for and one of them being not having to deal with little to no fallout. I'm also a firm believer in quality brushes that I only utilize with my makeup application. Can't have poor brushes expecting great applications in my opinion of course. I'm comparing my naked 3 to the previous editions I have currently and I was just disappointed with the looseness in some of the shadows (not all) when picking up the product with my brush. Not too long ago, I tried illamasqua shadows for the first time and it was a powdery mess! There are very few brands I stick with that I can say the quality of the shadow equates to the price tag and that's not always the case with high end cosmetics. Brushes I use are Mac, Nars, hakuhodo and a few Chanel.
