My son is a union electrician and I do residential wiring. Between the two of us we have a lot of cutoffs. I researched about a dozen machines and compared functionality and price. To me this was the best machine for the price. When we used it the first time it took a minute to get it setup and figure the best way to use it. Running the wire through twice appears to be the best way to remove the plastic coverings no matter the size of the wire. I would recommend this machine to anyone. It is not designed to operate eight hours a day five days a week but it is built pretty tough.
