  • They work great--but are a bit tricky
Size: 120PCS
I bought these because I do a lot of guitar electronics, and I was just getting tired of soldering wires together, then applying shrink tubing. These things are great; but you have to know a few things. First, don't expect that the solder inside will melt as quickly as you see in the ads. It melts, but it takes a while. Remember to heat all around the diameter of the connector, not just one side, for a more even distribution of solder, and better shrinking of the tube. Second, make sure that the ends of your wires are both long enough to reach to the center of the connector. just slide the two ends past each other, then apply heat. Not only does the solder melt to solder the two wires together, but the body of the connector acts like shrink tubing, and the two rings at either end of the connector shrink to help hold the wires in place. Third: heat. It is tempting to use either a butane lighter or soldering iron tip to melt the solder and shrink the tubing, but don't do it. The connector will start to melt (soldering iron) or turn black (butane lighter) The soldering iron can also melt a hole in the connector, which kinda defeats your purpose. A good heat gun is quick, easy, and leaves the connectors looking pristine and perfect. (The heat gun I use is about $20 on Amazon.) A note, though: give time for the finished connector to cool down--like a minute or two--before you test the connection by pulling on it. Also, use the smallest connector that will fit the wires you're using. Using a larger connector may seem easier, but the smallest connector you can use will make perfect connections. I've used so many of these that I'm going to have to order more--only this time, I'm going to get the BIG box... ... show more

  • I really like these but putting them together is a hoot
Size: 120PCS
I do a fair amount of connections where the connection is exposed to the environment. This seemed like a pretty good solution. I really like these and the fact that you basically get a Soldered, waterproof, joint is the best. The only problem I found is, trying to hold the 2 wires, in place, while trying to hold a heat gun to shrink and then melt the "Solder". Especially when working in a tight location. It's easy to get the wires in from each side but trying to hold them right where the solder part is and the man handle a heat gun too - you need about 4 hands (Last I checked, we only come with 2 as standard equipment) and most of the time you're working where even 2 hands are too much. Their worth having and work great - you just have to have patience and good luck. ... show more

  • Bout 50/50
Size: 250PCS
When they work right they work very well (use heat gun not torch) . However they only work correctly bout half the time the other half of the time the solder in the center does not melt making it weaker than a crimp connection at that point. Other thing is that they dry out fairly quick and become brittle losing their weather proofing farily quickly. ... show more
