I've used them a few times so far and they've worked everytime. The only downside I've had so far, is sometimes you can't tell when the solder has melted. They could improve on that. I like the adhesive on the ends, but would prefer an added crimp feature. I think that would help when repairing wires in tight spaced areas. ### ⭐⭐⭐⭐⭐ Everything is as described. *by A***R on Reviewed in the United States on March 27, 2023* Everything is as described, works as shown in the video. I'm very happy! ### ⭐⭐⭐⭐ easy to use holds wires eyogether xtra strong *by R***L on Reviewed in the United States on February 20, 2023* they hold great i like the extra glue for sealing!, the only thing I would ask is to put more solder in the ring --- ## 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.jp/products/388938415-500pcs-solder-seal-wire-connectors-waterproof-and-insulated-heat-shrink](https://www.desertcart.jp/products/388938415-500pcs-solder-seal-wire-connectors-waterproof-and-insulated-heat-shrink) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-07*
