I received this product a couple of days ago. I've had ingrown toenails for years and even surgery to remedy them. I had to use Google to search for a video on how to use the tool properly. Once I watched a couple of videos, I gave it a try and to my surprise, it worked like a charm. It was painless and my toes have never felt better. This tool really works and by the quality, it should last a lifetime. Wish I'd have found this years ago. I would recommend this tool to anyone with ingrown nail problems.
