I'm lining the elevated garden beds I made last fall with geotextile fabric to keep the dirt in but let water drain.
I have an Arrow T50P "Heavy Duty" manual stapler and I'm using branded arrow T50 stainless staples (1/4 leg). The thing is frustrating beyond belief. I can't count the number of times I almost hurled it into the woods. At least 4 or 5 times per "stick" of staples, it misfeeds or something and jams on a mangled staple that has to be pried out. If I don't then release the magazine and dump out the staples and replace them, it will just jam on the next staple. When I dump the staples, there is always a short group of them that has broken off which now has to be tossed. I am only putting full sticks in the stapler. I'm just stapling the fabric to the cedar wood I built the beds out of; it's not like it's oak or Ipe.
I have a pneumatic narrow crown stapler that never jams, but narrow crown staples don't work well with the geotextile.
So, if anyone can recommend a manual (or pneumatic, or cordless, but medium or wide crown) stapler that is reliably jam free, I'd love to hear about it.
