I read many reviews before buying this item. I was expecting the stapler to be expensive but was pleasantly surprised. Some reviews indicated that the gun would stick after a few uses. Has anyone considered the presence of a small amount of engine oil in the shutter and spring mechanism? I have a feeling that these people jammed the gun due to lack of experience. I did exactly that before I started using it and MAN! This weapon kicks, but while chewing gum! I had 2 small jobs and didn't even have to change the battery (probably 40-50 shots on each job). I've dealt with many different types. and various tools in my life so far and this little gun is definitely a great addition to my tool collection. Light weight No air hoses required No compressor to carry around
