As a big fan of MAC products, I have not been disappointed by the Technakohl Liner.

Retailling at £13.50, this eyeliner comes in eleven colours, although I must admit that I have only used the black ('Graphblack') shade. Now, £13.50 may seem steep for an eyeliner, but its creamy formula means that this liner lasts a long time (I've used mine pretty much everyday for at least three months and its got plenty of use left in it), and it really stays put, meaning you don't have to keep topping it up. Compared to cheaper mechanical eyeliners I have used, this is the only one (aside from Barry M's Intense Eyeliner) that hasn't broken if I've accidentally twisted it a bit too far.

As I said before, I've only tested out the one shade, but the black is a lovely deep black which smudges easily if you want it to but leaves a nice clean line if that's what you want. The one criticism I can think of is that it takes a bit of work to take it off at night; but on the plus side I've worn it in horrible rainy weather without ending up with panda eyes, which is always a good thing in my books!
