Review on 🔌 65.6ft/20M 22 Gauge Electric Wire: Ideal Extension for LED Strip Lights, Speaker, Doorbell - Red & Black 2 Wire Stranded Tinned Copper - 12V DC Wire by Monty Barganier

The wire is listed as "22 gauge tinned copper" but it is actually 23 gauge aluminum wire. When I received the wire I cut it and saw no copper at all. I examined it under a magnifying glass to see if it had a small or hard-to-see copper core, but I couldn't see it. So when visually inspected, it looks like aluminum (as opposed to "tinned copper" which is more expensive than regular copper). I measured the width of the wire with a micrometer and found it to be about 22.5 mils. is a 23-gauge wire, not a 22-gauge. I noticed that the wire's sheath says "22-gauge" but that's obviously wrong. I measured the resistance on a 20 meter long line and found it to be about 2.1. Ohm. This matches the resistance of 23 gauge aluminum (a 20 meter length of 22 gauge copper would have a resistance of about 1.06 ohms). Resistance to what they advertise.
