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.

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.
