These seem great little connectors. However I thought they were like 'chocolate' connectors, with each lever holding two wires (in and out). They are actually like a 'node' so each wire (2, 3 or 5) will be electrically bonded togethey. This is my mistake - but thought it was worth explaining.

Seems OK. Holds the wires very well. I tried with thin and large single conductors and it's fine. I was able to force unconnect it but that was with the wire wrapped around my hand and pulling hard (probably in the 10-20kg range). So unless you want to use that to hang yourself that's enough...
