I think this stuff is just ok. i have it in black brown. It does seem to stay pretty well on my eyes. I'm not a big fan on felt tips, but it works fine. I would buy it again, but i think i can find better. i really like my avon liquid liner.
Edit* the other day this stuff kind of burned my eyes, also it felt like i was putting a sharpie on my lids. and it did fade a little bit. I still dont hate this liner, but it is not that great.

Staying power is unbeatable. I haven't worn liquid eyeliner in a long time, since discovering cream eyeliner, but this is still the best of the liquid eyeliners as far as I'm concerned. The felt-tip applicator is much easier to use than brush-tips. I have been known to even dab a little of this eyeliner onto another eye makeup brush, such as a bent eyeliner brush, and then apply the product onto my lid. It helps, but I still prefer cream liners. But for what it is, Revlon's ColorStay Liquid Liner is really great.

this is one of the favourite eyeliner of my favorite make up guru "makeupgeek - marlena" i bought this after watching her tutorial and was completelly impressed ... love the application and colour , not at all messy and if u r not use to liquid eyeliners u will still be able to handle this one ...

I love this liner. I never liked liquid liners because they were messy and difficult to use. If you messed up, well you had to start all over. With this liner, it was so easy to use and I found myself hardly ever messing up anymore (probably just got used to using them).

I bought the liner in black/brown, it comes out a very nice rich black, but it's not like BLACK black. Which is why I avoided buying the color black. Usually the color black turns out too black or charcoal. Black brown always comes out a nice black that works for brunettes.

The liner stays on ALL day. No smudging or flaking. If you mess up accidentally.. Then it's extremely easy to fix with a q-tip and some water. I will definitely be buying again and again!

This is one of my favorite liquid eyeliners. I love that the brush is not flimsy and how long it stays on. The one thing that I dont like is that when I apply it I notice that it kind of streaks. I think its because the brush is pointy which causes your kin to show through the middle of the line. I have to apply this 2 times before it looks good.

I too have this in blackest black. I am a huge fan of this liner!

The applicator is easy and very controllable for a smooth line. In the short time I've been using it, I have had no problems with smudging or fading. The color is truly black, and has a matte-looking finish. This allows you to easily create thick or thin lines.

I am in love with this liner, and will continue to purchase it. I am a fan of Revlon products. This does not fail to impress!

I really love this one i've been using it everyday for a couple of years and love it, always get great compliments when i wear it never had any probs with it.

Ouch ~this, along with Prestige liquid liners has something in it that stings my eyelids. It's like I'm applying a low concentration of some kind of acid. I just tried the black shade, and I like how it's opaque enough that I don't have to go over the line drawn repeatedly. It dries fast and quite matte. Lasting power is phenomenal which is the best thing about Revlon Colorstay products. The applicator brush is rather stiff, although it has a nice point to it so it's easier to control the thickness of the line. Overall, decent results with very good staying power, but the skin irritation I get scares me off from using this product everyday/long-term. Gonna try and look for something gentler...

Completely awful!!!!! You might as well use a magic marker and line your eyes lol

I bought this cuz I had wanted to keep a back up eyeliner in my purse incase I ever had a emergency.....needless to say after using this yuck!!! Its not a true back imo its more a blue-ish black and no lasting power at all it completely faded with in 15min after I applied it...so very dissappointing=(

This has been the liquid liner i keep going back too. The precision of the applicator could be better, its not as easy to draw a nice line as some others that I've used. (meaning it is easy for me to draw a bumpy line that i have to go over) What it does have is a dark color, lasting power, and a good price.
