Don't like them. Of course, this comes from a guy who has a history of shearing the heads off of screws! Lets face it, the #1 causes of burned connectors in the 15-30 amp region is bad contact between the conductor and the plug. What I see in the spec sheet is a picture that has very little region of pressure contact. (Maybe a 32nd of an inch) The steel spring clip can not be counted on as a good conductor, so that leaves the area where the wire is in contact with the pin under pressure. Again, a very small area. We also know that even when new, conductors tend to have oxide on them, so the REAL contact area is even smaller! Give me a traditional screw anytime! Better yet, crimp, then solder (in that order only), then put it under the screw and add a split lock-washer!
