This is the first, and only lip liner, that I have so this review may be biased. But I do like this product. I'm not really sure how to review a lip liner, but here it goes, short and sweet.I use this to line and fill my lips, it's nice and smooth, and I've never had an issue with smudging. It makes my lips feel super dry after applying so I always moisturise my lips a bit beforehand, and then wipe it off.This lip liner lasts really long for me, and it holds my lipstick in place really well. I'm always worried about eating and drinking, but my lipstick stays perfect for a couple of hours (maybe about 4-5) before i need to touch up.I bought mine off ebay, and I think it was about $8, I can't quite remember, but this is a great product and goes well with any bright red lips, possibly even darker reds.
