I have used several of these connectors for different projects, including adding accessories to my RZR and fixing various appliances around the house. One of the standout features of this kit is its ease of use. The solder seal connectors create a strong, waterproof bond without the need for complicated crimping tools, making my work faster and more efficient. These connectors provide a secure connection that holds up well, even in tough conditions. I was particularly impressed with how well they performed when used on my RZR, where they faced exposure to vibrations, dirt, and moisture—yet the connections remained intact and reliable. For appliance repairs, the heat shrink design ensures a tight, insulated seal that has given me peace of mind knowing that the electrical work is protected. Overall, this kit has proven to be an invaluable addition to my toolkit. Whether for automotive, marine, or household electrical projects, these connectors have consistently delivered quality results. If you need dependable, high-quality wire terminals that are waterproof and easy to use, I highly recommend giving this product a try.

These make repairs so quick and convenient. I always prefer to solder rather than using a basic butt connector. I have employees that aren't sure how to solder, and these are perfect for them. The built in heat shrink makes them even better. They are so easy to use. Just make sure you have a decent heat gun. A hair dryer is not going to cut it.

I only use these for light electronics so far, such as splicing in a case fan to a power supply molex for a computer case. There isn't a lot of expectation of movement or tension on the joint, all I am really doing it for is to keep the connection and prevent any shorts from occurring accidentally. That said, even with my relatively inept skill at this, it does seem to do that job sufficiently. I was a little worried about the reports of people blasting through the plastic and splattering solder all over the place, which would be disastrous inside a computer case which is where this was performed, so I was very cautious and am not even entirely sure I did much more than a shrink wrap on the wires, though I think the solder did get melted onto the wires. It was hard to tell though. I gave it the light tension test of tugging on the wire to see if it seemed to come loose, and it did not, which was good enough for me. If this was expected to come under any real strain on any basis at all, then I would want more proof that it had worked, probably would have cut off the shrink wrap and looked to see that I was sure the solder had melted and it had worked, then cut it and do it all over again. But for my purposes, admittedly extremely light, it worked. I used a heat gun that I set to 400 F for this. I used a set of "helping hands" clips to keep the wires held up for the heat gun and moved the heat gun all around one side, then twisted the wire around in the clips and did the second side. It took a while to shrink wrap the wires, and again I am uncertain if it actually melted the solder, but again, my needs were limited. My lack of confidence in the soldering happening, the reports about solder splattering after melting through shrink wrap fear, and the length of time it took to shrink wrap the wires are why I ticked down overall rating, ease of use, and adhesion.

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...

They make things a little bit easier, & clean looking. I just now finally got to put them in use, in glad I got them, because I do not own a soldering iron any more, all I needed was a heart gun( or a lighter)
