Super flexible high copper wire with great conductivity
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.

Good for high temperatures, very flexible.
Nice wire for my application (antenna and high frequency design). Has a high isolation voltage, waterproof, and takes high heat. Very flexible, easy to strip. Many wires, so good conductivity. Readably accepts solder.

Good Wire
Good Coating on the wire, easy to separate the red and black, easy to solder. Has worked well on the projects I use it for. Would recommend it.

Good wire
Wire is great and at a great price point. Separating the two wires can strip the insulation off of both sides though. If you don’t have a need to separate much of them it should work great for you.

Great Product
Great product. Like all silicone insulation, it strips easily. Very soft and flexible, very "forgiving" when you have to bend, etc. My dad worked for GE Silicones for 30 years, and he would have appreciated this product.

Excellent wire for esc leads on high preformance race quadcopters.
This is perfect race quad esc wire.. it stays flexible so long as you don't let solder run down under insulation.. it carries current very well and doesn't get warm even when pulling 50 amp to each esc burst current on high KV 5 and 6s build... on 4s builds honestly 18awg is fine imho.. on 5s and 6s 1600 to 1800kv builds 18 will work to (16 is better and doesn't lead to bottle necking your power system) 16awg is a must if your running 2300 to 2600kv motors on 5 and 6s as the high KV and high voltage will cause extreme current draw... on my 2600kv F40 Pro V2s (they handle 6s fine, so long as you keep prop weight and pitch in mind.. stay with a 4 or 4.3 pitch prop MAX on 6s... 5s safe to 4.5 pitch props) 6s will pull over 50 amps burst on 6s 95c 1550 R-lines but the battery can only sustain that for a second or so then sag and prop unloading will start to pull current down. This is not a race setup this is speed run setups and working the power system very hard for quick bursts of power and only 2 to 3 quick runs on a charge not to mention it kills batteries like no tomorrow... I have started going to 1800s to make batteries last more then 20 cycles before IR starts to rise quickly and pack doesn't have punch anymore high C rating 1800s will last in the 80 cycle range and top end preformance will suffer none due to the batteries being able to fight sag much better then 1300 or 1500s.. point of all this is if you are running stupid high wattage power systems that pull tons of current at high voltage this 16awg wire is up for the task.. it's very high quality wire that holds up to those harsh attacks of current draw and don't get warm cheap wire will get down right hot because it carries a lot of resistance and this wire does not.. in fact on super light race builds I use the 16awg as main lead wire to save weight and it serves just fine so long as it's a short run of wire, on my 5 and 6s high KV builds I run 12awg because 14 or smaller will melt solder joints because it can't carry current that quickly.. on 180 to 200 gram dry weight builds with 2204s or 2205s for small tight tracks i always run 16awg wire and the power leads don't even get warm after a race so this wire will stand up to 40 to 50amp constant and 70 to 80 amp bursts on a 3 inch run of wire easily being it's not even getting warm it could handle more.. that's a good way to tell if your wire is bottle necking your power system, if the wires are mildly warm then you could prolly get a little better preformance from going one size bigger wire... If it's down right hot then you need to go two sizes bigger... If your melting solder connections... well then your need much thicker wire lol and learn to not build super thick solder joints as that is a place of increased resistance.

Very good quality wire
Very pliable. Easy to strip and solder. I am creating an LED project and using this as the wire between LED groups.

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.
