I have 1/2 dozen or so wire strippers, crimpers in the toolbox, but none really did 90deg 1/4 spade connectors well. I figured I'd invest in this as an adder, and if it worked for that, great, if not, another crimper in the toolbox. I had a chance to use this for the first time when crimping yellow insulated terminals on a pigtail for an old Ford Blower switch/pigtail with 10 Gauge wire. The good: tool itself is sturdy, ratchets are fine enough, and grab very well to crimp anything you put in there. Box is good. Grip is good. The bad: the insulated terminal crimp die is not good. It makes/leaves a flat crimp, not a U shaped crimp. The flat crimp is no better then pair of pliers. The best crimp die for an insulated terminal is a deep U, where the terminal slit is bent into the U, as you'll see on Molex and other connectors. It works OK if you don't have anything else, but the U shaped crimp in a wirestripper tends to make a better crimp that folds the terminal into/over the conductors. Overall, the tool quality is great. Insulated terminal die leave room for improvement. Other bare terminal dies are good.

I bought these to help me with wiring harness for motorcycles and cars. They work great. I had to buy the additional spark plug piece but I wish there was more room inside the box for the additional dies.
