Query: Sounded good but didn't work for me either...

I tried using the acid products several times without success, so I was really hopeful about the effectiveness of this product. I thought it was similar to the liquid nitrogen applications you can get in a doctor's office. Unfortunately it didn't quite do much for me. Even though I applied it 3 times for the maximum time recommended (40s), it didn't hurt much at all and didn't blister, so the warts are still there... It doesn't seem like any over the counter products are effective for plantar warts!
