had seen these at the store but never gave them much attention
looking on online retailers there are a lot of different makes and models
the one pounders just seem too light for 16d nails seems like they would rattle your hand off or make it go numb but the heavier ones weigh in at 3 pounds and i wonder if that is even enough mass to absorb the shock
also wonder how they do with smaller nails
they make a lot of sense especially for those tight spots like between studs
there is a cordless model also but i forget the brand and they are pricde higher
