Blaze SolarActive Polish

Have you guys seen this nail polish from SolarActive called Blaze? It changes colors in UV light, and it looks really awesome! I would really love to try out this polish; I love some of the colors but I just love how it changes colors with the light. I know I've seen other brands which do this as well, but I've never owned any. I saw this in Prevention magazine today and just had to look it up, and of course had to share :)

So I'm wondering if any of you have tried this brand? Is it as neat as it looks? Is it worth the $12 or so it costs?
