I make money in construction and switched to this gun as our old one finally gave up. It was a bit strange at first switching to this weapon after using so much with the positive nail placement design. But I got used to it quickly and now I like it a bit more. It seemed that with this design and the inability to see where the nail went, there were more chances for a ricochet. However, I had no problem getting nails shot in my face. The nails seem to stay on track better, I think this is because they only shoot 1 1/2 inch Teco so there is less room in the track for the nails to move. The only real problem I've encountered. Nails don't sting, it's when the nails are hammered into a knot, but that's understandable for almost any gun. In summary, I would say the Pro'sGun is quieter than the last pair we used. The nails stay in place. The air hose attachment bracket makes it very easy to put on and take off the air hose. The weapon has less recoil than the others but is still just as powerful. Does not have a built-in hook. In thick winter gloves you have to hold the weapon with your fingertips. .
