The best invention for fixing wires that mankind has ever made.
My god these things are the best invention mankind has ever come up with. Seriously whoever invented these should have a statue made of them and put in every town in the country.If you do any kind of tinkering or electronic repair, or just like to mess with stuff you NEED these in your life. I’ve been a tinkerer all my life, I like nothing more than fixing and messing with electronics and have been soldering for about 30 years but these are a game changer. Just strip the ends of the wires and push each end into the correct size tube and heat with whatever you use, I use a gas powered Dremmel portable soldering iron. The solder strip in the middle melts and solders the wire and the 2 seal rings shrink and seal the wires from water. The joint is amazingly strong when done right and is very neat.These are great to use in tight places when you don’t have much room like when your working on a vehicle.I absolutely love these and will always have them in my tool kit from now on.

Heat shrinking tunes.
Excellent product ideal for joining electrical wires.

Brilliant
A great secure way to connect the wires just heat up the solder and securely does the job no mess

Not great
Good idea but these are let down by the lack of solder in the middle. Solder content needs to be 3-5 times more as when heated the amount of solder just isn’t enough to run into the connection properly
