What really makes Sub-Zero stand out from other thermo polishes I've tried is the amount of shimmer and flakies in it. The polish has green shimmery flakes and very fine copper shimmer in it, making it change tone depending on the light as well. The flakes and shimmer give it depth and work perfectly with both the blue base and the black base colour. It's also the only thermo polish I've come across that actually almost always makes a visible transition effect while in room temperatures.
I have acrylic nails at the moment, that might affect how the thermo effect works, but on my nails it's absolutely gorgeous. When I go out, the polish turns dark, and when I come back in, it makes my nails have a lovely smooth gradient from blue to black.

Sub-Zero is satin finish, but glossy top coat makes the polish even more vivid. You need 3-4 coats to get an opaque result, but the polish goes on nicely and does not streak easily. I've been wearing Sub-Zero only for two weeks and I think I might neglect my other polishes because of how wonderful it is!
