Review on Waterproof Heat Shrink Tubing ELECFUN by Jeff Jackson

I bought this for very infrequent soldering jobs where bending the leads when placing them on a breadboard can be tiring and eventually break tiny soldering tips. It works great for this task. The smaller size fits snugly around the 22 AWG lead wire and solder lugs to protect them. The larger wires were then compressed around the three wires on each side of the DPDT switch. No more worries about flimsy solder pins coming loose as soon as I need a switch.
