Smashbox is a pretty decent brand, and in the grand scheme of things, they do tend to be a little bit on the pricier side. Things that they do well in are: shadows, brushes, lipgloss, lipsticks, Softlights in Shimmer.
A lot of the other stuff, I find though, lack in quality compared to other brands. A lot of people love their Photo Finish Primer, and while it definitely works on a lot of people, it breaks me out. And I would kinda be weary of using their foundations and stuff too, because they are a photography company, and their foundations are meant to last under hot lights and stuff like that...and really, just for photoshoots that are a couple hours long. Probably not too good if you wear it everyday and you're not diligent with removing your makeup.
OH and their mascaras suck too lol.
