Hi-Res is a scattered purple holo from the Milani 3D Holographic collection, which consists of 6 polishes, all of which I own. I love purple so I'm very biased when it comes to Hi-Res. While the holo effect isn't as strong as other holo polishes out there, it's still very evident and gorgeous in the sunlight and indoors. It's much better in person. The best apart about this polish is that it only cost me $4.
The formula was really good. It was thin, easy to control, and fast drying. It can get a little patchy, as some holos do, but it has yet to cause a problem for me. It is sheer but for me, it was good at two coats but I did three just to be sure.
I recommend Hi-Res, as well as the rest of the collection, to anyone who wants a holo that is both gorgeous and affordable. I believe you can still find them at CVS, but if not, they're on the website, Cherry Culture and retail for $3.99.
