I bought these to solve a 4 wire problem - the nuts are not holding the 4 wires. My original solution was to use 2 wire nuts and have a jumper to connect the two. So each wire nut had 3 ends. Why 4 wires? The bathroom panel has a light switch, fan and heat lamp. There is also an incoming wire to connect the other 3 to neutral. WAGO solves this problem with a single connector and without jumpers. I can't run a wire as the timer (for the heat lamp) and fan switch have their own wires, not screw terminals. I didn't doubt my wire nuts, but I knew there was a better solution (thanks You Tube) that didn't require additional wires. Consider that I bought a 36-piece set for a 5-slot WAGO and you'll see how much I care about my home. They are worth the price for wiring projects only. Since my house skin is in game, I recommend it.
