This wire performs exactly the way good silicone wire should. I used it to replace several stiff furnace wires that kept overheating and melting terminals, and the difference is immediate. The silicone jacket makes it super flexible, so routing it through tight spaces and around corners is simple. It bends easily and stays where you position it. The copper content is excellent. The wire has a very high strand count and you can see it as soon as you strip it. The tinned copper strands are packed in tightly and give the wire strong conductivity. Voltage drop is low, the wire stays cool, and all of my connections feel more stable than before. Because of the strand count I had to use the 10 gauge slot on my stripper even though it is labeled as 12 gauge, but using light pressure keeps the strands intact. Thickness and insulation feel solid without being bulky. The jacket handles heat well, fits standard terminals, and crimps securely. Once installed in the furnace it showed no signs of softening or discoloration. Functionally it solved every issue I had. The old wires were stiff, overheated, and hard to work with. These are easy to route, easy to crimp, and give reliable connectivity. They would work just as well for appliances, RC batteries, automotive wiring, 3D printers, or anything that needs flexible high quality wire. For two 30 foot rolls, the value is very good and I would buy it again.

I first ordered from a different vendor who said "Copper Wire" in the listing but it was actually copper-clad aluminum, which was stiff and bulky with a higher resistance. Sent it back and ordered this one, which I am very happy with. The jacket is high-quality silicone and between that and the many tiny strands of real copper wire this cable is super-flexible (floppy even). The silicone resists soldering temperatures without burning, melting, or shrinking back from the end. The wires are tinned over copper so they look like aluminum but they are definitely copper under the tin. Only about 0.3 ohms over the full 50 feet so great for high-current loads. Would definitely buy again.
