When the darker shades gets blended out ,its starts to look sheer :( i guess thats normal so it is more wearable,but you just keep have to applying and layer it up if you want a more dramatic look.
Use a blending brush and just blend!!!!
Quality wise ,i would say its average.I didnt like the fallout when applying the shadows on my eye.

With this quad,its best to do eyeshadow first then the rest of your face.

This shadows lasted me about a few hours - i kept on touching up on my outer corners because i went for a smokey effect.
