Got this item the first week of July. After fourty (40) days, I can see my nail bed (bottom of the nail). I spent three months using a topical anti-fungal with NO results. Now, after this relatively short time, I have more than half of my nail back. This is progress in my mind. You do have to use it multiple times each day, and scrub the area with mild soap, but yes, I'm VERY happy.
