Just buy it!
I never write reviews, but this product is amazing! Gave me instant relief after months of pain, and my nail is growing out nicely. I'm a senior and had a little trouble applying it to myself, but my husband got it on my toenail the first try and it's lasted for weeks. I'm looking forward to using it on other toenails which could be potential problems. Be sure to carefully read about choosing the appropriate brace tension. A big "thank you" to whoever invented this and made it available to purchase!
