This is one of my favorite tools, ever. I work as a commercial electrician and rely on my tools for a living. I use this clipper for cutting any gauge i need to cut on a day to day bases, anything from the #22 up to #4. Flip it over and It also works great for cutting tape without nicking the wire.
Sadly my 1st pair didn't take very kindly to cutting a live Romex but it still functioned fine and is now my spare pair
