Great product
I purchased the entire set last year. I wore the braces for a little over 6 months while my toenails grew out. I was able to go all spring and summer without the braces. My toenails started curving in again and I knew it was time to start wearing the braces again, so I purchased the braces and a new bottle of adhesive. I've been wearing them again for a month and my nails are flat again. I'll continue to wear them until the entire nail grows out again. I know the product will work because I've seen it for myself.
