This is the summary of consumer reviews for NYX PROFESSIONAL MAKEUP Epic Ink Liner, Waterproof Liquid Eyeliner, Black. The BoolPool rating for this product is Very Good, with 4.20 stars, and the price range is $6.29 - $9.00.

The NYX PROFESSIONAL MAKEUP Epic Ink Liner, Waterproof Liquid Eyeliner, comes highly recommended for its incredible precision and deep, dark line it creates. The pen is affordable yet dupes as a high end eyeliner, and stays put like one as well. The brush tip glides gently over the skin, and makes it easy to create a smooth line or to make sharp shapes as necessary. 

Customers say this product is great not just because it is cruelty free, but the brand is a great price for the quality of product. The waterproof liner stays in place all day and compliments any sharp look.

Some say this product may drop in quality over time, including a fraying brush tip and a drying out product after some use. Overall, though, these issues seem few and far between.
