I have been using Airforce for five months and I am very impressed by the results I have seen. I have been restoring off and on for many years. I have tried many devices over the years and discontinued using them because I saw slow results or they hurt to wear. Many times, a combination of both. Before I started using Airforce, I managed to progress to about C1-4 to C1-5 coverage. Since then, the progress I have made with Airforce has been amazing. Don’t get me wrong, it has taken a lot of work and effort. I have been very dedicated to wearing Airforce as many hours I day as I can, along with using a ball stretcher when I can and wearing a retainer anytime I am not restoring. But If I had not experienced the results I have seen with my own eyes, I would not have believed it was possible to see such impressive results. I can honestly say, if you really want to see results, Airforce is for you!
