Clever splice

How's that any different than the shrinky-gooey crimp connectors that auto parts stores have been selling for years? Edit: there lives ultra-low melting point solder inside. I'm kinda meh on that. If it needs solder, it needs to have the wire replaced. I'll keep my crimpy-melty ones from the parts store for now.

Nasa splices are da bes splices, if you have the extra wire.
