“Dreadful disappointment: flyweight punch, air-hammer loudness.”
The NEXTEC Auto Hammer should NEVER be used w/o ear-protection: 3,600 impacts/minute produces a noise greater than a chainsaw. Unfortuneatly, the impacts are about what you'd get from lightly swinging a tack hammer so there's very little resulting total impact. I can turn my hammer sideways & produce a greater impact when there's "little space to swing a hammer" & get the job done much quieter & quicker. Even an electric staplegun has more impact. The only real use I would have for it would be driving brads into picture frames...IF I had a LOT of softwood picture frames.
