The original wire has served well in 25 years of use. I'm handicapped and refuse to pay $50,000 for a new truck (it won't perform as well as my 1994 anyway). Give them a chance thanks to the reviews. I was very pleased with the high quality of this "real copper" wire, not coated aluminum - COPPER!, very well tinned, the silicone insulation is real industrial silicone. I run all my wire in a braided nylon sleeve and secure it every 24" with heat shrink tubing with adhesive over all connections - works very well with this wire, easy to shape for tight turns, once laid lays straight, excellent (above notched tin helps here) I now have several hundred feet of 18, 16, 14 and 12 gauge of this VERY high quality wire (also used in my solar system now). Thanks again to Revane for another "Top Quality, First Class" product that I can deliver to my door 90 miles out of town. And thanks to everyone who takes the time to review the products, we could all benefit if they only knew better what their strengths and weaknesses are.
