These quads are of great quality. The colours all work wonderfully together to create either a subtle or bold look depending on how heavy-handedly you work. The highlighter shade in my quad which is the "07 Over The Taupe" is excellent. Very creamy and not chalky at all. I find the 2nd darkest and darkest to be my favourite though although I must say the transition colour is wonderful as well.
I do find though that you have to layer the product to get a very pigmented look as they are not as intense as some of the other essence eyeshadows. They work wonderfully on the go as a travel quad. You get 2 mattes and 2 shimmers which are your basic shadows for creating an eye look with some depth.
I just wish they had a much wider colour variety. I have only spotted 3 so far. Mine, a warm neutrals one and an emerald one. I would love to get one in Maroon shades, purples and blues and maybe one super shimmery, glittery one to add dazzle to your eyes.
