Good but slightly disappointed...

I am a lover of a good eyeliner with my favourite pencil being benefit bad gal, but I have never found a liquid eyeliner that will stay put without smudging onto my brow bone. After doing a lot of googling this eyeliner seem to come up as the best so I went in and bought it. Now don't get it me wrong it's a lovely texture and glides on very nicely. The assistant told me it was the blackest black but to be honest it is no blacker than any other. And even now I still having it melt and sometimes smudge onto my eye socket. Good, but I can't believe no one else has had the same issue.
