Review on 💪 Strong and Resilient: SD13 3Pin Waterproof Connector for Reliable Connections by Corey Krull

Nothing in each soldering pin holds the wire in place when soldering. Don't know how to connect! I've resoldered many connectors over my years - they always had tabs that could bend over the wire next to or in the soldering area. It's not like this. Two stars because otherwise they look good. If you can figure out how to hold each wire in place while soldering it to its pin, they should work fine.
