Review on 100 Pcs Solder Seal Heat Shrink Butt Connectors, Waterproof And Insulated Electrical Wire Terminals Splice By TICONN by Pradeep Dhimal

Quick, solid, and easy connection if you have a heat gun. Slide in bare ends and apply sufficient heat to shrink the outer casing then keep going to melt the inner metal and you have finished making a great wire connection. I rewired my trailer with these and am very happy with the ease of use and the final connections. I need to find something more precise than my shielded heat gun to help place that heat source more precisely on the joints if I want to use them around wood or plastic.
