I did it, I've worn this polish for 14 days and despite my previous disbelief I have witnessed an improvement. It claims to reduce chipping and splitting, leaving nails stronger and harder. Well, my nails still split as much as ever but my nails are actually loads thicker, which means less chipping for sure. During my first week of wearing the polish the nail on my right index finger split right the way across, going back half way up my nail so I was a bit annoyed at that, but maybe it had to get worse to get better. Since that incident things have gone well. So well infact that this morning I have reapplied the same polish as it's a nice clear coverage that generally just makes my nails look neat. Perfect as a base coat too.
Verdict: Not too shabby.
