I bought two kits the smaller one first, (which was so successful that my daughter promptly took back to her uni house), followed by the bigger unit which I've managed to keep at home! The instructions are easy to follow and the results are salon professional, and long lasting with no chips or broken nails. (I last did my nails three weeks ago and they still look fantastic, despite my hands being immersed in dish water, chlorinated pool water, and detergents of many kinds!) I'm not terribly girlie by nature, I don't have the time or the money but I love the results with these kits and I wear the nail gell more often than not now as a result. They are easy to use and I can achieve salon results for a fraction of the cost! Win win don't delay! read more
