    • Good product!
Size: 120PCS
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. ... show more

    • 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

    • Works great if you are careful with heat
Size: 120PCS
I was going to give a negative review because the plastic kept melting away before the solder melted, but then I got a better heat-gun with adjustable heat. The sweet-spot seems to be around 400 degrees F where you can melt the solder without burning away the plastic. My old heat gun had a constant temp around 600F and that was just too hot. Take your time, let it warm up slowly to 400F, and all will turn out fine. I find it helps to smear some solder flux in between the wire strands before joining them in connector. This helps to pull the solder in between the strands once the solder finally melts. Con: I really don't know why one end is narrower than the other... makes no sense to me. I end up having to use the next size up, but then the solder ring is way-too big and doesn't melt all the way sometimes. I had to remove one star for that. ... show more

    • Work so well
Size: 120PCS
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. ... show more

    • These are what you need
Size: 120PCS
If you follow the directions these work very well. I stripped the wires. Used a wire brush to make sure the wires were clean. Made a hook on each end to make a strong physical connection. Then using a heat gun, rotated it around the connector until the solder flowed. Making a stong waterproof soldered connection. Can not ask for more. I used these to redo a fuel injector harness for a 95 F-150. Ohmed out the harness before wrapping up and was good to go. These should last for years. I did use heat shrink over the connection. To shield them from heat generated by the engine. I have used a similar brand before. But these were really good as well. I have recommended these to a friend already. And gave him some. He had excellent results as well. ... show more
