Rating : - Relatively inexpensive and it works well. I bought this stapler a few years ago when I was running some indoor/outdoor carpet down some wooden stairs (a perfect application for the rounded staples). I have since used this gun for many projects - inluding wire tacking and various other projects using both the rounded and square type staples. I have not had a bit of trouble with jamming and this gun seems to have enough force to drive stables into any type of wood construction material. Also, I paid less for this gun at a local hardware store than it is listed for here (sorry Amazon!)
