The heat shrink insulators worked as expected but the solder never melted to join the wires together. I tried high, medium, and low heat at varying times and the solder never really joined the wires together despite overlapping each other. As I have observed, the only reason why the wires got connected is because the heat shrink insulation shrank around the wires thereby tightly putting them together. The solder? It was hardly affected by the heat from the heat gun. I don't think it's even genuine soldering material. Will I by this particular item again? NO! I will try a different brand. ### ⭐⭐⭐⭐⭐ Very strong. *by J***N on Reviewed in the United States on April 3, 2018* I had never used these before so I was a little iffy when purchasing them. I tested them to join two pieces of wire and wow, very strong. Once I melted it with a heat gun I could NOT break the connection with my hands. I pulled very hard and it did not come apart at all. Ended up using various sizes of these to replace the wiring to my Jeep fan speed switch. ### ⭐⭐⭐⭐⭐ Makes nice tight sealed butt connections with little effort or mess *by J***F on Reviewed in the United States on February 9, 2019* Not as much work as soldering and heat shrinking connections but just as good or better without the mess or precautions necessary when soldering. Much easier than soldering and more accurate than hand crimping unless you have an expensive hydraulic crimping tools. I heat shrink the ends to ensure the wires wont pull apart then just enough heat to melt the solder or if you use the helping hands tool it doesn't matter where you start. Have not had any over melt as other reviewers have mentioned and most my connections look like nicely tinned solder connections. --- ## 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.hr/products/36436582-premium-solder-seal-heat-shrink-butt-connectors-kit-of-50](https://www.desertcart.hr/products/36436582-premium-solder-seal-heat-shrink-butt-connectors-kit-of-50) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-17*
