All electrical work depends on a good mechanical connection and this tool appears to make one of the best mechanical connections I've seen. A dap of solder and a piece of dielectric shrink tubing then a protective boot snapped in place and this connection will out last the wiring.
Some photos of acceptable connectors in various parts of the world
almost the only type of connector used in house wiring in the middle east
very popular in the USA
My preferred after a connection is tightly twisted, if the wire is stranded I like to solder as well then these are crimped over the connection
I was told the reason the U.S. Electrical Code prohibits soldered connections is that too many people think "soldering" is laying two wires side by side and running or globbing molten solder between them. The lead, silver, tin of the solder melts wasily and can result in an open or short circuit or fire.
It does take a good mecanical connection to make a good electrical connection.
I like this tool!
Some people simply stick the stripped ends of wires to be joined in a "wirenut" and twist the wirenut. I never did trust that type of connection and always tightly twist them before inserting in the nut, otherwise you are expecting that little steel spring inside to conduct the current of the joint.

Not all wire nuts are created equal many don't even have the conical shaped steel spring in them, just plastic threads which may or may not be OK I only know that I don't like them and don't trust them even when having the ends firmly twisted prior to their use
Many years ago at a Home Improvement store which has since gone bankrupt, I bought a piece of wire made by Carol Wire to replace a cord on a bench grinder. It wasabout 10 feet of 12/2 with ground in a heavy orange jacket. Got it home and put it all together and a couple of weeks later when I went to use it, it wouldn't work. So naturally, I opened each end and saw no problem. Checked and had voltage at one end of the cord but not the other. So I began to dissect it and found the neutral white wire had been half soldered together and had broken. I took the cord back to the home improvement store and they called me a liar. Never went back there.
I'm looking at this and I see a huge problem.
I used to wire wrap square posts with 24 gage wire. It held it like glue. But as soon as I wrapped the same wire with the same wire wrap gun on a round shaft post. the wire slid right off.
So I see it as not good mechanical connection . I never done it but as you wind a spring on a medral , You know that the spring wire spring out on diameter of the mmendral. Just me thinking on this boring day.
