I used to own the bronze,peach and rose then gave them away. I prefer Smashbox Softlights, not as much shimmer and depending on which one more colour.
Shimmerbrick is really a highlighting product, you can use individual colours from the palettes as eyeshadows. But it can give the tin man look quite easily trouble is people don't notice this themselves. Look at Alison Young, remember a light hand. Shimmerbrick just won an award on beaute.ie(voted by the public) as best highlighter. Oh and there is also a reason by they never demo it on QVC on old models if you notice.
I do own the blender brush, got mine when much cheaper when the first Shimmerbrick was brought out cost £19 back then. I use it mainly for blending down blush if I think I have been too heavy handed.
