I have been using the 2true Waterproof Eyeliner for a while now and really enjoying it, but when looking over the Collection 2000 products I saw this and remembered that I used to use the Fast Stroke eyeliner all the time a year or so ago, so I picked one of the Waterproof Fast Stroke Eyeliners from the range.
I like my eyeliner to be completely opaque if I'm wearing a liquid liner look and this didn't deliver that on the first or even the second go. It took quite a lot of going back over, but I'm not sure if that's because I have eyeliner issues and am a bit fussy.
I really like the handle for the eyeliner as well. As it is really long, you feel a lot of control over the application. Sometimes when applying it a bit thicker with the edge of the nib, I found that the thinner part of the nib would almost draw a line through what you had just applied where it was removing a bit of the product. I found it lasted well on my eyes, and yet was easily removed, so you aren't left scrubbing at your eyes like I sometimes find with waterproof products.
Have you tried the Collection 2000 Liquid Liners? If so, I'd love to know what you though!
