This is the first time I’ve used this type of wire for building and repairing electric guitars. These 22 AWG stranded silicone insulated wires are perfect for connecting control pots and switches. They are soft, flexible, and the insulation does not burn or melt back when soldering. The wire itself is tinned pure copper and solders with ease. I use a silver bearing solder which requires more heat than standard lead/tin solder. The silicon insulation handles the heat just fine without burning or distorting it. The wire is strong and durable, yet it strips back easily with a standard stripping tool. They are true to the advertised thickness of 22 gauge. I have used both traditional cloth insulated (pull back), and PVC insulated guitar hookup wire in the past. I will be using this silicon wire from now on. It is easy to work with and produces a very clean professional looking result.

Seems decent but is very flimsy if you have to run it through any narrow passages.
