Just by looking at the wire and holding it you could tell its the real deal. Solid quality and very flexible. Im sure when I finaly instal it, my amps will run way more efficiently. The only thing I recommend is to figure out a better shipping rate and method. 5 ft of 4 awg and 5 ft of 01 awg were both 10$ even making it 20 all together. I dont believe that was accurate, at least for the 4 awg wire. Seemed a bit high. Not to mention I live in Florida... Im sorry but there is no way that 3.4lbs of wire would cost 20$ to ship in the same state. It was literally about the same price as the wire
