Rated 5 out of 5 by from Fabulous Colour I don't normally go for red nails but this colour caught my eye. The nail varnish glides on and really does strengthen the nails. I had a lot of comments about how shiny and fresh it looked even after a couple of days wear

Rated 3 out of 5 by from Great colour! This nail varnish is a great colour and glides on easily but has chipped after two days which is disappointing

Rated 1 out of 5 by from A disappointment The varnish was a dream to apply, it looked great and I was initially delighted. Unfortunately it chipped from the edges and wore away from the tips of the nails really easily within a day or two. It might be viable if you had a really effective varnish protector but without that it's not worth the hassle of continually having to 'touch up' or re-apply.
