This is for EL eyeshadows in general.
The eyeshadows were reformulated in 2010 (?) and now have better staying power and pigmentation than the previous reviewer noted.
All limited edition palettes are the same quality as their singles, which is different than lots of other brands who often stick in lower quality versions in limited edition sets (I'm looking at you...Stila)
That said, if you can get a Holiday Blockbuster with a palette, or a GWP, give these a try. I know EL doesn't get a lot of love in the North American beauty world as lots of people see it as old lady makeup, but the quality is outstanding and the blend ability as well as the colour range is outstanding.

(Note that Estee Lauder owns MAC, Clinique, Bobbi Brown, Smashbox, etc so maybe the great formulation is from t hem all using their great ideas...)
