I've had enough of Arrow T Series staplers stalling all other staplers, feeding multiple staples at once or otherwise not working and I decided to try GB after 30 years of problems with many rifle guns. So far I'm not disappointed at all. I already have an almost full box of staples and they never got stuck or messed up. Given the way the staples are made, loaded and fed, they're not likely to jam or misfeed like the Arrow.
