    Best wire connectors we've ever used!
  

*by A***A on Reviewed in the United States on December 13, 2016*

These solder wire connectors are so handy and easy to use. It took a bit of practice. I think we ruined two of them before we figure it out. You slip your wires in like you would any connector (I like to overlap a bit in the middle), then you heat the connector focussing mainly on the middle first, where the solder is. You can heat it by your own preference but I used a lighter, be careful and use caution to not completely scorch the connector. Here's the important part: have a set of needle nose pliers ready because you will need to gently press the part that has the solder immediately after heating to ensure that the solder completely seals the wires together. Then you can continue to heat the ends to snug up the rest of the connector on the sheathed wire. I don't test it until it has completely cooled. Made the mistake the first time of pulling on the wires to see if it was going to hold and it all came apart. I also did not use the needle nose pliers the first time either. After figuring out how to use them we have used several of them now as we are in the middle of rebuilding a car and there were many places to use these, we have decided that these are the best thing since sliced bread. Love them. Highly recommend them. What's really nice is that you have a clean finished look that does not require electrical tape or other mess looking methods. These look neat, clean, and hold extremely well.

    Makes a great soldered connection
  

*by R***D on Reviewed in the United States on September 15, 2023*

Purchased these Sopoby solder connectors to make water tight connections on my trailer. They've lasted a year now and haven't had any problems with my trailer lights. I also used heat shrink tubes over them really making them water tight.
