I haven't been paying attention to the booster function so I cannot comment on that, but as a liquid eyeliner it is just excellent! The tip is very fine and it is so easy to control. The colour stayed on very very well throughout the day. Even when I was outdoor on a very hot day, it still stayed on for the whole day. Having said that, it is also very easy to clean and wash. No ugly messy smudges at all. I have to say I am very impressed and would highly recommend it. Will definitely buy another one if this one goes out.

gives a fine line. it fades out during the day but no more then other similar products. make sure to store it upside down or it will dry very fast.

I like it! great price, nice product. pretty dark brown color, easy to use. stays on for a whole day, but be careful - it's not waterproof!

creates a nice, smooth line but you should shake it or something first to make sure the "ink" reaches the tip and goes on nicely.

I've always a fan of liquid eyeliner. This product is easy to use and it has soft but sharp brush. Though I have always used the colour black and since this product is deep brown, you can tell the difference btween brown and black. Will definitely get black next time. BUT great product, don't let my bias of loving black eyeliner stop you.

I am not sure about the effect of eyelash. I don't use it everyday. I am positive to the "eye booster" effect. it gives your eyes a nature and soft look. n not difficult to remove the makeup.

Love the deep brown as it matches my brown pupil. Good for people with sensitive eye.

This is my second purchase! Not sure about the lashes growing longer but the liner is good quality and easy to use. The price is fair as well, will continue using.

Love the fine tip and the fact that it makes it easier to apply as close to the lash line as possible. I have a hard time seeing up close and I have no trouble putting this eyeliner on. I close my eye and go by feel for the top lid. The tiny precision point makes it super easy. I will order this again. I haven't used very long so I am not sure about the eyelash enhancing ability. Too soon to tell. My only concern is how long it will last. Time will tell.
