I own Revlon's just bitten in Desire and Passion. As a product it is awesome!! It stays a considerable amount of time, even if you eat or drink, it might wear off eventually but you still have that little burst of natural looking color on you lips all the time. I use Desire in an almost daily basis, I apply it before going to work, I usually work 8 hours, and I rarely have to do a touch up. I like the very natural looking effect it gives to your lips, imaging when it's REALLY cold outside and your lips get that blushy color. The balm is also very good, it adds to the color that shiny look if you want it to look a little bit more as a lip gloss, but I prefer to use a regular balm with no shine. I even use it as a base color and apply lip glosses, especially with shy colors, over it, that way the color really lives up.
I don't use Passion much, it is a very hot pink, better for night events, it has that 80's look also, or maybe it's just me. I forgot to add that the lipstain doesn't feel dry, and doesn't crack your lips. Overall, it's a really good product. I would definitely recommend it.
