These lever nuts are worth every penny. The 5 pole nuts make wiring an M.Unit, where multiple wires need to connect to the same output (Ground or AUX2 for running lights &c). They are so much faster than crimp connectors or solder and so much better than twisting wires together.
So handy for quick changes in wiring configuration. Seem to have strong enough grip but I’ve not had them on the bike long enough to tell.
