Review on 🔌 ESUPPORT 4 Pin Way Car Auto Waterproof Electrical Connector Plug Socket Kit: 10-Pack with Wire AWG Gauge - Ideal for Marine Use by Matthew Watkins

They work well but the quality isn't very good. I bought 2 packs for an LED lighting project. In one of the connectors, the black and red wires have been swapped. Unfortunately I didn't realize this until after I had it connected (based on the red and black wires) and then realized that of course 1 row of LEDs was not working. This included cutting the shrink tubing, desoldering, re-soldering, and refinishing the shrink tubing. (Long story short - check your cables!) I also had problems with a pin coming loose in another port. They've only been plugged in a couple of times, so it's not due to overuse. I couldn't reinsert the stylus (even after removing the red retainer) so all I have to do is manually reinsert it after connecting. These are still decent connectors and worked well for my setup. to test and problems may arise.
