Most commonly described online as a pizza cutter, the Mac Rollerwheel Liquid Liner is a teeny, tiny wheel that promises to apply the finest and most defined line of your life. To be fair, it does. However, you have to be so precise about how you use this unique applicator for that to happen.
Basically, your hand has to be exactly level with your lashline, and since the shape of your lashline is curved, it means you need a very steady hand; bracing it on a flat surface doesn't help much because it limits how well your hand can follow your lashline.
Also, I'm used to a brush-tip or a felt-tip, which bend with the pressure of my hand and allow me to manipulate that pressure to apply my eyeliner. Most liquid liners work for you, whereas with the Rollerwheel, you have to work for it.
It's one of those products you have to get the hang of before you love it, and I actually do love the formula. It's a gorgeous opaque black that stays on and won't budge. There aren't that many liners I can put on and know I don't have to worry about it for the rest of the day, and this is one of them. I still haven't mastered its applicator though, so it's a liner I only reach for when I have time to spend on my make-up. But since I'm *ahem* chronically running late, that's not very often. I'll probably continue using it, but dip my precise liner brush in the product itself instead of using its Rollerwheel applicator.

I was super excited to read about this product which seemed to offer an easy way to get super-fine liquid line. I was even more excited when one landed on my desk.
Sadly, it just didn't work for me. The formula stays put once applied, which is obviously a major plus, but it's the actual applicator which, sadly, I could not make work on my eyes. I think the wheel might actually have too small a circumference - because it's so small, it doesn't cover much length very quickly, so the liner it holds tended to run into my eye instead of delivering liner across my lashline as I drew it across.
The unflexible nature of the wheel also means that it's difficult to build up a thicker line by drawing on top of the first line - you can't really direct the applicator very easily.
If you're super dexterous, this is probably a great way to deliver a thin, long-lasting line, but if you're remotely ham-fisted, you'll get fed up too quickly to see such results.
