This has been the best liquid liner I've found thus far and I use it daily. It lasts all day and it's not hard to wipe off. The thin brush helps with easy application and precision. Because it's so reasonably priced I usually grab 2 when I buy then so I always have a backup. I highly recommend trying it for yourself.
Recently picked up the (non waterproof) mascara and immediately I can tell it already lived up to its claims! I'm so glad I went ahead and grabbed it! It leaves your eyelashes elongated. Definitely a must have in your makeup case!!
