I've been loyal to this eyeliner for a few of years now, when I first started wearing makeup the only thing I looked for when purchasing was the price tag, bearing in mind a 15 year old doesn't exactly have the funds to have a makeup bag full of the top of the range stuff. And I've got from mascara to mascara, foundation to foundation but I've never found another liquid eyeliner that compares to this one!
Though I do not have sensitive skin on my face so I cannot comment on how it may effect someone who does.

ABOUT THE PRODUCT
****************
I buy mine from Boots, at a very reasonable £2.99 though at other retailers I have seen it sold at £3.99, though I still wouldn't complain at that price. (You can often find it in 3 for 2 deals also).
It comes in a small black pot with a 'handle' extending to about 3 inches long, and about the circumferences of a pencil which comes in handy with trying to put it on and you feel comfortable with the handle!


THE APPLICATOR
*************
Unlike most of the liquid eyeliners it is more of a soft felt nib that you dip into the liquid, rather than a brush that goes frayed quickly or ends up clumping.
The rod that the nib is stuck onto is quite firm which means (if you have a steady hand) you will get a smooth line easily.
You do sometimes have to wipe excess liquid off on the side as you take it out if you want a medium line, otherwise for my personal taste it's a little thick.

LONGEVITY
*********
Well, in terms of once it's applied how long it stays on your eyes, it is fantastic! The best one I have ever tried, my friends often buy expensive ones (i'm talking £15-20) and mine is on a lot longer than theirs and if you don't mind me saying, I think mine looks better! It doesn't crack or flake off even on nights out.
In terms of how long the product lasts with every day use, I'd say about 6-8 weeks. (though obviously this will change with how much of it is used at once and how often it is applied.)

REMOVAL
*******
Although it stays on fantastically during the day (even when it's raining), when you attack it with a make up wipe it comes off easily and smoothy with no black stains left behind, or hard rubbing to force it off.


I love this eyeliner and would not use another one now, the value for money is amazing. You get a smooth long lasting finish and it takes a couple of seconds to do! I very much recommend it.
