This colour-change nail polish seems to be much better than others I've tried. It may take a while to dry, but the colour-change aspect works very well and doesn't involve magnets which I don't feel to be that good. The blue/purple suits me best, there is a pink option and a gold, but I'm not a fan of those particular colours. I do think them better quality than a lot of other nail polishes. To sum up, an easy to apply, though slower drying nail polish, with a nice finish and colour-change that works well.
I really do not believe that this item is worth the money which I paid for it. The chain itself seems to be silver plated and of reasonable quality, but the pendant itself is a real let-down. It feels poorly-made and is insubstantial, very thin and, I do not believe, to not be of very good quality. It looks cheap, and the web image is not a good representation of the product itself; it gives the impression that the design is domed, and that the design is a brighter colour, both of which it is not. I would return it, but as I won't have my return postage refunded, I do not think I will bother. Don't waste your money.
I generally like China Glaze polishes - usually good consistency, good colour range. I bought this thinking it would come out as a green/blue mix with a sheen, however I was disappointed - it turned out to be a light wishy-washy green with hardly any hint of blue in it at all, even in different lights. The consistency was rather gloopy, so difficult to apply properly. A shame the customer image wasn't available when I first looked at this.
