Rimmel ScandalEYES Waterproof Kohl Kajal Eyeliner is a longlasting liner that is "waterproof, smudge-proof, sweat-proof, heat-proof, humidity-proof, and scandal-proof". (Wow that is a lot of "proofs" to live up too!) The two shades I bought were Black and Nude. They are around $4-5 at a drugstore. I got mine in a Buy 1 get 1 50% off. These applied very smoothly and are very pigmented. I don't think I've ever had a black eyeliner so black! Since they do apply smoothly, they are on the soft side and after about two days, I need to sharpen them. 
<--------- Here is my eye makeup in the morning.
And below is my makeup 6 hours later. There was some traveling and it did run into the inner corners and almost gave me "raccoon"eyes on the bottom.
(L-R: water on Black, normal Black, smudged Black----smudged Nude, normal Nude, water on Nude)
So how about those claims we read earlier? Well, it is water proof to an extent. It won't rub off when water is applied. However, in my water line, it does end up washing away a bit. I live in a hot climate were there is heat, humidity, and of course that brings about sweat. As far as smudge proof, it failed for me. I don't like when my eye liner smudges and runs all over my eyes. So since it smudges, I really don't know if it is heat-proof, humidity-proof, or sweat-proof.
Would I repurchase? No. I've been looking for an eyeliner that won't budge throughout the day, and sadly this was not the one.
