Using a heat gun they provided and it was super easy to slip it on, twist the wires and slip it back on to solder and seal in one swoop is wicked cool! Very happy! Gave them
William
Verified Buyer
Work excellent! Seal AND solder wires together! I just hit them for about 15 seconds with my heat gun till shrink tube shrunk then solder melted to wire leads...boom, done!
Brad
Verified Buyer
This solder sleeve works exactly how it is described & kills two birds with one stone of soldering wire as well as sealing the connection. It is a huge time-saver.
Kevin
Verified Buyer
After about 5 seconds the rubber material started to shrink. At about 9 seconds the solder started to melt & bond the wires. I gave the wires a firm tug & there were super tight.
