I highly recommend this cable only recommend especially for the price. Of course I can not come up here with any technical measurements, with regard to the quality of the cable, but it does the job. It is supplied as a coiled ring. The cable is color Although not marked but it is the insulation on a wire flattened and round at the other, so you can distinguish positive and negative well even for longer distances. The strands of the cable are relatively fine, of course, not as fine as with expensive cables. The insulation is also relatively soft, which makes installation easier.
