Very nice product. Silicon insulation means it is very flexible, not stiff like most wire. I was able to easily run it around my engine bay from the battery connection at the starter to a relay I installed for the fuse box, neatly tucking away most of it from view.

This wire actually exceeded my expectations, it is very soft flexible and seemingly durable and carries the current very well. We use it to power the aircraft that we work on via a 13.8 VDC TekPower switching power supply capable of 50 amps. So far we have used this wire to a capacity of about 15 -20 amps maybe a little more at times and it didn't even get warm. We are using the full 25 foot run of both the black and red for this set up (see the attached picture). The voltage drop across the full 25 foot run is surprisingly lower than what I thought it would be under a full load.... at an approx 16 amp draw the actual voltage drop across the wire was less than a volt, (like around .7 - .8 tenths voltage drop). We have only been using this now for about a month so I can't say how durable the wire will be over the long haul but so far it has done very well for the minor abuse we put it thru. The attached picture is current to date and we have used this on many multiple airplanes so far. Over all a very good purchase, I would recommend this to anyone needing a heavy wire to carry heavy current loads. Also we soldered our connectors at both ends to minimize any further voltage drop and the wire worked very well with the solder. Very Happy with this purchase! On another note..... I would most likely not use this wire for any type of welding gear as it is not pure copper wire, just my thoughts. I will update this post if anything about the wire changes, durability etc.

I needed some extra cable to run power from my trucks battery to the rear battery and on to the inverter. To differentiate between those and the normal 12v system, I choose this blue cable. It's nice and flexible, has a heavy cover but thin strands and is mostly aluminum. Not a big problem for me, but if you're going to run it in a heavily used high current draw circuit, pay for the full copper wire.

The cable is copper clad aluminum, but for the price, who cares! 25 feet of 8 gauge cable for this price is almost a steal. I run a 4 gauge into a splitter and come out with two 8 gauge cables going to two Rockford Fosgate 500 watt amps and the included wiring has worked well and served it's purpose. The cable is easily ran as well do to it's flexibility. Can't beat the price of this stuff either!
