I got the turquoise color for Hatsune Miku! It's very nice, bright, and sparkly.
My only complaint might be that the size was a bit smaller than anticipated, and the color was a little greener than pictured, but it's still very very great! My favorite part is the customizability; the plastic tube on top can be unscrewed to swap and combine the screens/filters inside to add pictures! (This was the tutorial I used! http://monta.moe.in/wp/2013/06-09/23-49_1067)
All in all, the product is very high quality and perfect for idol concerts <3 miku expo, here we come!
