I didn't hold out much hope for this product, so only ordered one. In fact it is excellent. The secret is its ability to hook behind the remnant of the broken nail to form a firm but flexible 'nail' to pick with. You can sand it down to match the length of the other nails, or to your ideal length. I immediately ordered two more and now don't have to suffer the paranoia surrounding nail care. Obviously they aren't as sensitive as a natural nail, but they provide a great solution to a broken nail.
