This is Magenta Color Flip, 2 coats, with topcoat. Apparently the Color Flip range is the Color Blast duochrome range. This one shows a gorgeous red/orange in the bottle, which suckered me in immediately as I LOVE reds and oranges!
Application is really nice - it's even, smooth and clean, and the brush is really good. The lid is nice - it's rubbery and the ridges give a good grip.
On the downside, I can't really see any duochrome on the nails. There's a bit visible in the bottle, but it doesn't really translate to the nail.
On the other hand - it's a gorgeous, glowy, shiny colour! I do really like it.
Having said that, £9.50 is quite a lot for a high street brand, and I can't say that this colour is particularly unique. I do have a lot of glowy metallic reds! But this is beautiful!
