Review on ELifeApply Waterproof Electrical for Underground Installation by David Pirlet

Easy to use three way connectors. My outdoor garlands were torn apart when the tree they were on fell during a storm. I used them to put them together and they worked like a charm. It was enough to just connect the wires to the terminals and screw the caps nice and tight. Be careful not to twist the O-rings. Now my headlights are like new and most people don't even see the connectors until I show them. Highly recommended.
