and they've done pretty much all of them right for something that's priced at less than ?2.50 per metre.

The main sleeving on the cable is extremely durable while remaining highly flexible and easy to strip.
The two internal cables are comprised of a large number of very thin copper strands which means less wasted volume due to a circle's inability to tessellate and much easier winding/soldering as the copper is extremely supple.
The sleeving on the internal cables is also great quality and allows for very easy stripping without bringing copper strands with it.

All in all, it's a cable - a great value, great quality cable that's very easy to work with.
