I love these things. They provide a good, firm grip on the wires, are fairly easy to use, the length of the strip is molded to a side with some specs and gives a visual indication of how deep the contacts are inside the case. The levers require a lot of force to open and close and they snap which can cause you to lose your footing, get pinched/hit by the lever or scare you half to death. This makes them a little more difficult to use (literally), but they require no tools and keep the ladder…
