It took a few tries to get the hang of it. It takes multiple attempts on the same spot to get the dent out but it does work. 90% of the dent is gone leaving only a small dent where the actual point of impact was.
This is a high-quality machine worth every penny spent. I had a project that I put off for a while because I could not find a machine that could handle the work needed. FINALLY, I tried this product and it worked like magic. It perfectly pulled out all dents.
