They are very good. They’re easy to use and the solder in the middle melts relatively quick. I just used a harbor freight heat gun and it works perfect.

Works great, good quality easy to use.

Awesome price and work great to keep wires sealed and dry. Super easy to use with a heat gun.

Product is worth your money and works surprisingly well!! One key point to remember is USE FLUX and don't rush the process, it needs to heat to be able to work. I use a pen style heat gun that has a metal heat reflecting attachment for the end as opposed to a traditional gun style and it works very well also don't just heat spot rotate the heat around the connector once you achieve necessary temperature you can watch the solder flow and you will know that it has done its job!

These are very handy 100 times better than crimp style connectors

I have a Christmas light show and have lots a pixels, and when the weather is bad, some go bad. I used to have to bring out a soldering iron, solder, heatshrink and lighter to make a repair. Now all I do is twist the wires together, slip the sleeve over the connection and heat it up with the lighter. It doesn't take a lot of heat, and it melts the solder making a good connection, and shrinks the tubing over the joint making it weather proof. It's been a game changer for me, I wish I had found it sooner. This size works well for my led bullet pixels, but I also got the assorted sizes for other projects. Good stuff!

These are great. Perfect connection and hold. Great value
