Easy to work with. Used to replace prior wiring for a sprinkler system. Old wiring had become oxidized at the sprinkler terminals. Got tired of cutting of the ends and reconnecting. Not sure about the heat rating but it was 115 degrees Fahrenheit when I installed. Doubt there is enough current in sprinkler system to get the wires warmer than that. I am happy with the product and would buy it again.I ordered two rol!s of wire, one black and one red, each 10 feet. They sent what I asked for and added four more rolls. It also comes in the cool box above with holes (I have the yellow poking out), some shrink wrap and some cable ties. The wire is tinned and so very easy to solder. Hard to beat at the price!I installed some LED Fog Lights in my truck that required some re-wiring and this wiring come in handy. Its easy to cut, splice and bend. Made the job so much easier! Overall good quality and great price!Highly flexible and quality wire, though very thick jacket, 5' is very shortLooks like good wireWorking with these silicon wires was a little unnerving since they will be exposed to high temperatures on a truck. They are just as listed so only time will tell if they hold up. I really prefer rubber coating.Flexible, easy to cut and strip, solders perfectly. Buy some and happy wiringMakes it easy to build flexible cables.Purchased this for a small modelling project and its just right. Comes with a very handy dispenser/Tidy box. Very good value for the price. I would recommend this easily.Why do they always blow the picture up to make it look big they should keep it normalNice and soft wire 600v. It was exactly what I was looking for at a good priceUpdate so I have waited for months now for my free 6 rolls of 6 foot wire for my review and pic . There is a card in box saying this and I have message them and they say no stock will ship when they get more .... I reorder again cause I need more wire same card and same thing without fulfilling there end .The silicone sheath of the wire seems good quality .The wire has many many strands making it very flexible, soldering it works but solder doesn't flow to it as it would with copper.Joint still works and good conductivity so no dry joints.Overall works but next time I'll stick to copper.Seller offers free samples in return for a good review which is deceptiveMuy buenos cables para pequeños circuitos, yo estaba acostumbrado a agarrar cualquier cablecillo que me encontrara jajaja principalmente los de los cables ethernet que usaba en la universidad a diestra y siniestra, pero usar estos cables suaves es completamente diferente, todo es mucho más fácil, se pueden tomar de forma muy sencilla al momento de poner la soldadura y además los puedes acomodar super bien. Yo los use para reparar unos audífonos y un Nintendo DS y fueron perfectos para el poco espacio que queda dentro de dichos dispositivos, pude acomodar los cables dentro de ellos sin problema.
