I bought this staplegun when I had a lot of fence to build on the ranch and my arthritis would scream after pounding a dozen staples. It was a great solution for that. Sadly, fence building is still a lot of work.
It comes with a hard case complete with two batteries, both AC and car chargers, tool for gun maintenance, manual and about 400 staples, plus two fuel cylinders. I ran about 3500 staples thru it and the gun truly beats pounding them by hand, especially when you are north of 60. Now, I'm just fixing fence a few times a year and it isn't worth keeping this gun just for that.
The staples are 1 3/4" and barbed, which really helps them stay put when cows are pushing against the wire. One thing I learned after having some misfire issues, was that the gas cylinders need to be fresh, ideally less than a year old. A service rep explained the butane is pressurized by another gas in a bladder which can leak out over time and cause misfires. Once I understood that and used current gas cylinders, I had no problems at all. The included gas cylinders are old, so if they misfire, get a new one. Cylinders are good for over 500 staples.
This is a great gun, if you have a lot of staples to drive, especially if you have arthritis.
