Revlon Colourstay Gel Envy Polish & Diamond Topcoat - A Disappointment!

It's not often I write 'Disappointing Products' posts but I just had to mention this one. I was really excited to see these two in the Latest in Beauty box as I've wanted to try one of these polishes for a while. I loved the colour so it's a shame it didn't work out.  At first I was really impressed though. Application was great and the finish was so shiny. However, just a day later it started to peel off in whole chunks. I've got a feeling the topcoat is to blame here as I've experienced this problem in the past with others, especially ones that offer a high shine. This wasn't my biggest gripe though. When it came to taking it off I discovered that it had stained my nails really badly. I would have expected this normally but it claims that you don't need a basecoat. Lies! At least with this bright shade.
So yes, I'm disappointed that it didn't live up to my expectations but I'm going to try it with a base coat and a different top coat as I do really like the colour.
