poor design and bad build
Crutchfield Customer Review (What's this?)
Almost impossible to open and close with one hand. Very stiff . Wire cutter location defeats the advantage of leverage. I used it with 12 gauge speaker wire and no way could it cut the wire. My kitchen shears were far more useful. Strips wire well if you can get i to close using two hand and hold the wire in the right little slot for the gauge at the same time. No way could my wife ever use these.
Cons: impossible to use with one hand, does not work for cutting thicker gauge speaker wire.
