Indeed it works great! It saves me so much frustration, gives a sturdy connection and works with one or two hands. When soldering a butt end connection, I usually need 4 hands. 2 to hold each wire together, 1 to hold the soldering iron and another to feed the solder. Quite a hassle. I have to get creative with tape or clips. These wire connectors make it easy. I just slip it on one wire, twist the wires together and center the sleeve. A heat gun or lighter gently melts the glue holding the wires together and finally when it gets hot enough the solder flows. If the wires don't hold together, you can always readjust it before the heat shrink/glue bonds permanently. Work from one side to the other.When I soldered in the past I would always get frustrated when the solder doesn't flow where I want it to. I finally found out about oxidation. If the wire ends are oxidized solder doesn't want to wick through the wire. This is not the fault of the wire connectors. Ensure a fresh cut with a newly stripped butt end. This along with a tiny dab of flux ensures perfect soldering every time. The only thing I'm wary of though is that I don't know the long term effect of acid flux sealed inside a waterproof connection. It may corrode over time. I guess one could use an acid free flux or prime the ends first making sure to burn off all the flux before connecting. The good thing about this is that the connectors are clear and colorless allowing for easy spot check of the joint. This is especially useful in awkward spots like under the dash in a vehicle or in tight spaces. You just have to figure out how to direct the heat without impacting surrounding components. ### ⭐⭐⭐⭐⭐ Great for diy projects! Time saver *by J***Z on March 15, 2019* I was somewhat skeptical about buying this item because of some reviews I read while shopping for solder heat shrink. I must say I am completely satisfied with my purchase. This 170 pc kit comes with a great assortment of different gauge wire heat shrink. Great for DIY projects that require soldering wires together! Real time saver as you solder and heat shrink at the same time. As of now I have no negative feedback on this item. Have used it twice and has worked great both times. I have included pictures on my install. I will say there is some condensation inside but that is completely my fault for using two different gauge wire and a torch. I will definitely recommend using a heat gun! I used a torch for the convenience of not having to run an extension cord for my heat gun but I will for sure use heat gun next time! ### ⭐⭐⭐⭐⭐ recommend it! *by F***I on August 5, 2019* In the past, I had to solder the two wires with the solder iron, and then use a heat gun to shrink the heat shrink tubing to wrap the copper wire. Until I found these on Amazon, it is really time saver, it just took 30 mins for me to finish the joint, while it would take about 2 hours to finish the same joint via using the old way. Though it is a little bit expensive than the heat shrink tubing, I will recommend these solderless wire connectors. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/169996955-160pcs-solder-seal-wire-connector-kit-kuject-solderless-and-crimpless](https://www.desertcart.us/products/169996955-160pcs-solder-seal-wire-connector-kit-kuject-solderless-and-crimpless) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
