So far I just have this in Hot Pants, kind of a strawberry red/pink with no shimmer or glitter. It's got a decent amount of color, but it's not overwhelming. Just a touch and my lips have a bit of color and shine, and a bit more and I've got more drama.
There's a faint scent -- extremely faint -- and it's a touch sweet, but mild enough that it doesn't bother me and that I can't quite place it. There's a sweet flavor, too, which I find pleasant, as it's not medicinal.
The feel is close to vaseline, but lighter, and smoother. It feels comfortable, like a slightly slicker balm, but doesn't feel heavy, sticky or distracting to me. It's just nice, and a very pretty color.
Staying time is decent. It will last through a bit of coffee and wears evenly. I'll notice an hour or two later that I still have a good amount of product on and that it feels moisturizing.
Update: I picked up three more of these: Tomboy, which is a red-brown; Adjust Your Tiara, a sheer purple; and Berry Go Round, a berry pink that has a tiny amount of blue shimmer. All three are very pretty and wear comfortably. The Tomboy has more pigmentation and gets pretty opaque. The other two are a bit more sheer than Hot Pants, but build up (some).
My main struggle in store was deciding on a color to try -- swatching several on my hand, I found myself wanting a half-dozen, at least -- but I'm very happy with this color. And I like the product enough where I see myself picking up a couple others. They have a good range of colors, too, from pinky-nudes, pinks, corals, brown, brown-reds and berries, even a yellow gloss, and a blue and some purples, to there are options that are great for wearing alone, or for adding to another lip color to add some more depth or smile-flattering brightness.
For $10 it's a really nice product. I like these much better than some pricier glosses to be found at Sephora and Ulta, and they're definitely nicer than ones I've found at the drugstore for a couple bucks less, both in terms of pigmentation (good, but not crazy intense) and comfort/wear.
