I purchased the Cherry juice version of this product. I've listed some pros and cons below.

Pros:
-The gradient looks natural

-When you want to "buildup" the effect by adding more lip tint on your lips, it's a gradual buildup, not immediate

-The effect lasts for quite a while (a few hours)

-You don't have to worry about it staining cups/glasses when you drink (or food)--it doesn't stain

Cons:

-Can be drying; I'd recommend applying vaseline or lip balm before putting this lip tint on.

-Since it is a water lip tint, it can get on your teeth (that happened to me the first time I tried this on)

-It might exaggerate your lip lines; meaning, your lip lines/wrinkles will look more defined. I don't really mind this, but some people do.

Keep in mind that according to the packaging, the product should be thrown out 12 months after the first use.

Is it worth buying?: I think so. Even if you're a bit curious, and it's your first time dipping your feet in lipsticks, lipglosses, liptints, I'd recommend this product for people who are looking for something that will look natural on the lips.

Would I consider buying this product again?: Probably. I'd look into other liptints, but I really like this product. Personally I think the Cherry juice version of this product looks great for people with fair skin trying to pull off a natural gradient look. You can also use this product to pull off a more dramatic look and tint both lips entirely.
