I have used the captive screw tighten back stab devices and find them pretty good. But the same method is employed on most gfi outlets out there today. With gfi's the captive plate is so thin and cheap it sometimes does not hold the wire in place so well even if I super tighten the screw down. As far as back stabbing goes - whoever you are out there that does it- thanks for the many many service calls I have gotten which I fix in record time and get my 1 hour minimimum, and service charge. In the future could you guys not do it on the receptacles behind the heavy dressers? Your making my back sore.
