I've use Sephora lip glosses before, and while they're not my fave, they do a good job for the price. I remember them being a bit minty-refreshing when you put them on, but the nice thing about them is that they aren't terribly sticky.
This clear one is a dear ringer for MAC Lipglass, and less sticky too.
I've used the eyeshadows, nail polish, eyeliner (ok not great but I'm partial to Benefit's Babycakes), eye makeup remover (the only one i use), nail polish corrector pen (awesome!), makeup remover pen (also awesome), lip liner (only one I use b/c they are $4!), lip stick sealant (old formula was better than newer formula), makeup brushes (work great for me!)
I've been wanting to try out a lip gloss but always buy other stuff when I'm there. I would think they'd be good just based on my experience with their other products.
