Review on Wago Lever Nut 221 415 Conductor Connectors by Jacob Richmond

I wanted this item to work well and save me the wire nuts. Unfortunately they didn't work well. The wires came out several times. And yes! I made sure to insert the wires until they couldn't go any further. I even tried wrapping the plugs and wires in electrical tape to keep them from coming out of the plug, but one or two still came out. Not sure if this batch was defective or premature but they didn't fit me. Also, according to the label on the plastic bag they came in, it appears to have been part of a set that was sold separately and separately. Instead, I decided to go back to In-Sure push-in cable connectors or standard cable nuts.
