I purchased this staple gun in order to do some very light work, running ethernet along the baseboards of a rental unit. I was driving the smallest staple type into soft woods. I used genuine Arrow T25 rounded-crown staples. Power was ample to the task.Unfortunately, this staple gun really does jam on every second or third staple. It took me three hours to do 15 minutes of work. I think my record was getting through five staples without a jam.I should have spent the extra $10 for a dedicated round-crown staplegun and not messed with this dual-purpose thing.
