I've used the following:
Some Kind-a Gorgeous: Crap. One shade definitely does not match all. From what I've heard, it doesn't even match the majority of skin tones. It applies weird and feels almost slimey. Not a fan.
Posietint: Pretty, nice as a lip stain, but hard to blend quickly for the cheeks.
BADgal Lash waterproof: My favorite mascara ever, the only thing I truly love from Benefit.
High Beam: Nice as a highlight, but can be too shiney sometimes.
"That Gal" brightening primer: It doesn't so much brighten as it does make your face shiney.
The packaging is cutesy, but the products are overhyped and not worth the dough.
