My nails were beyond hopeless. I work in a store that sells skin and hair products and I was embarrassed to demonstrate lotions with my customers. Not anymore!!!!! A girl at work told me about this product and now I'm telling you to go and buy it!!!!! My nails were yellowed and dull from a summer of polish and I had even shelled out money for a mani/pedi and I'm telling you, the results after 15 minutes with this buffer were better then any natural manicure I've ever had! Please buy this, you'll love it!!!
