Review on Sopoby'S Waterproof Solder Connectors - Complete 140PCS Kit For Marine, Automotive And Home Wiring by Michael Glassburn

I was skeptical about these but so far I'm impressed with how easy they are to apply. Only time will tell how they do in the long run. One bit of advice is to use a heat gun instead of an open flame. The shrink tube can melt quickly if you expose it to flame too long. I got much better results using the heat gun that a lighter or torch. But yeah, I'll buy these again - soon.
