China Glaze Instant Chemistry is the last of the three Magnetix polishes that I got a couple of months ago. (You can see the first two here.)
I definitely had the most trouble getting the pattern to show up with this one and the final result is more subtle. The color is really pretty, a very dark metallic berry, so I don't mind too much. On the other hand, if you really want to see the magnetic pattern stand out (and why else would you be buying magnetic polish?), I'd recommend going for one of the other colors in this collection.
It turns out that Pull Me Close was my surprise favorite from this collection. What did everyone else think?
