I needed to repair some tiny wires on my granddaughters headphones that her rabbit chewed. The solderstick was the answer to fixing them. Wonderful product!

Easy and solid way to make connections. Arrived ahead of time and the communication was very good.

I needed to repair a break in a wire on my car that was in a very tight and hard to access spot. Not only did it work great, but the repair took me literally 2 minutes to do. Very pleased.

Great, easy to use product.

I worked in Electronics Manufacturing, Troubleshooting, and Support for over 40 years. First in the aerospace industry and then in commercial electronics. From my experience, i can tell you this is and excellent product and I highly recommend it for anyone looking to join wires simply with minimal tools.

Best wire solution!!!

I used one of the 10-12gauge size and three of the 14-16 gauge size when replacing the hvac fan resistor and resistor harness in my 1988 Ford F250 truck. I'm glad to have full use of my truck's heater fan now. I didn't pull hard on the completed connection, but it seemed plenty strong. I recommend these connectors.

A Must have for DIY

I'm doing a lot of DIY projects for my car, bike, and some home applications. Since I saw this a while ago on a project online I wanted to give a try. These are wonderful connectors with 4 different colors which will be enough for most of the projects you are doing. Heat-shrinking is easy to use, quality is great and they are really cost-effective! I highly recommend for those who are using connectors very often.


These are AMAZAZING! They seal great using a BIC lighter. Just make sure to move the lighter back and forth never lingering in one spot for more than a second (Pretty much the same as when you're sealing any shrink tubing). I was surprised to find that the solder ring melts very uniformly every time making it look like an expert solder weld consistently. It only takes about 4 seconds of waving the lighter flame before the solder ring melts so the whole process is much faster than expected.

Great on boat

The ease of use has really simplified some of the electrical projects that I was working on in my boat. Really cool idea with the solder in the connector for a VERY strong connection.
