I've been really impressed with this liquid liner. I was looking for a bright blue eye liner, and while the brush/well format is not my favorite, this was one of the few I found that didn't look like it would just be a dark navy. While the colour isn't as bright cobalt as pictured, it is still definitely a bolder blue. I have found the applicator to be pretty easy to apply as it has a very fine brush tip. The product comes out pretty juicy, so I find it best to start in the middle of my wing and disperse the product into the shape I want from there. As for wear, I was very surprised. I have hooded eyes, and it's not uncommon for eye liners to transfer to my upper lid over the course of the day. This one has not budged. So far I've only used it maybe six times, so I can't speak for how long the bottle will last, but as of now I would repurchase and I plan on getting the purple one too.
