Review on Connectors Sopoby Waterproof Automotive Electrical by Aaron Franklin

They do what they have to do. I set the heat gun to 650F and use a shrink bezel. A minor annoyance is that the heatshrink tends to *stretch* along its length when heated, pushing the wires apart slightly. A bit of a learning curve to get the plug wire spacing right and account for that stretch. Use them to connect power and data connectors with 20AWG wires for multiple strings of ALITOVE WS2811 RGB LED Pixel Lights (https://www.amazon.com/dp/B01AG923EU/ref=twister_B075F76BPV?_encoding=UTF8&psc=1), which we will be using in the Christmas lights this season. These solder connectors work damn well once you get used to them.
