Review on Rustark Connector Terminal Barrier Connecting by Aquarium Lanter

I cut the cross section of the spring quick connector to see how good the spring connection was in the connectors. pretty good. I've seen similar devices listed elsewhere with a maximum recommended power rating of 300W (my limit would be more of a wall power supply for hobbyist electronic circuits). Definitely not 250V, 10A, 2500W! I wish the screw connectors were screw connectors, not just screws.
