This says that the resi. backstabbers are 3x as reliable as the others. How can that be?
Let me make it clear one out of 4 is damaged from back stabbing devices not the backwired devices that will make the diffrence there I have more issue with backstabbing than backwired or screw in termails for the amout of time and troubleshooting it it almost automatic once you know what era the house is set up and type of device it used you can pretty much dail in and go from there.
P.S. Thank god for France they do not have any backstabbing devices at all !!!
