Review (5/5): Great, but not waterproof
I bought this from my local Ulta a month ago to treat myself. It works fantastic for it's intended purpose. Just be careful with the thick side, when they say "thick", they aren't kidding. The thick side is shaped more like a chisel Sharpie, so handle with care. Not very waterproof, but if you want waterproof, they do carry a waterproof liquid eyeliner (look for the blue packaged one). But all in all, a great product for it's price.
