Review on 🔌 Enhanced Efficiency: Black Duck Extension Replacement Electrical Connector Solution by Lild Zimmerly

I bought these to hook up some extra lightbulbs for work. They looked pretty heavy and had some decent reviews. What I received was disappointing. The lugs for the cables have nothing against the cable slipping out on the underside, 1 screw on the 1st connector from the pack was stripped straight away. It might work for a lamp cord (even then I'd hesitate due to the lack of securely held wires), but something substantial is out of the question. Lesson learned and $20 down the drain.
