Review: Great value - Great value and way cleaner and nicer quality than the regular parts store bits
Review: Some of the best crimpers for uninsulated terminals - First JReady product and so far so good. Really impressed by the build quality vs cost. These crimpers are an absolute joy to use. I spent many hours trying to find something that did uninsulated terminals (22-26awg specifically) reliably. Majority of crimpers in the automotive field lack the ability to do them, which is frustrating given all the smaller gauge control wires on modern vehicles. The ratcheting mechanism makes sure you've finished the crimp fully and the gauge will come in handy for future adjustments, if the need arises.
