Never had toenail problems before. Tried a cheaper product for several weeks and it did nothing. Used this for over a week now and already seeing an amazing improvement. One nail looks normal again, gone the yellowy ridgedlook. The other appear to be healing too. Obviously a good product and worth paying the extra. It comes with a special little file also and maybe that is the key to the solution getting into the nail and working. The pink polish is very pink but okay for summer. Would have preferred more choice than just the bright pink or red. I normally wear a rose colour. Overall very pleased and would recommend. One friend has already asked me to order some for her as nothing else has worked.
