So much for a good tool. Haven't used it extensively yet, but it's well made and shoots staples pretty well. However, it does have a unique exhaust sound after the clip is fired. Instead of the usual "catchii" sound, it sounds "catchpfuoo". Almost flatulence. Maybe it's because it's new and the o-rings are tight? IDK, but still works fine. Seems like a good buy for a quality product. The time will show.
