I cannot tell you how tired I am of following behind electricians who treat wire nuts like Bic pen caps. Open a box, pull out some wires and off goes a wire nut. Note: not the new house problem, this is the old apartment in the city. There must be a better way, right? Wire nuts just seem lame. Not hard to use correctly but often used incorrectly, wrong sized nut, wrong gauge wire, etc. So digging around, I found these connectors from a company called Wago. Anyone use them?
