I am an electrician but do very little residential work. I always used nail in straps the few time I did use romex. They, as we all know, are pretty miserable to use. I bought a Romex staple gun years ago (I forget the brand) and it worked okay. They quit making the staples though. Then, I bought the GB Cable Boss gun. It never worked properly. 2-3-4 tries before I even would get it to fire a staple. I saw Milwaukee had this stapler but put off buying it because I didn't want to spend the money for something I wouldn't use all the time. I suffered with the Cable Boss as long as I could stand to.I finally broke down and ordered this Milwaukee stapler and man, it is well worth it. It just plain works. No drama, no misfires, no problems. I even ordered generic Cable staples, and it still works flawlessly.If you do even a moderate amount of residential work and use romex, this is a must have tool and you will be so thankful you bought it. If you're like me, and will not use it a lot, it's still worth it.I highly recommend it!
