A bit thinner than advertized: Copper core is 0.5 mm thick each instead of 0.75 mm as advertized. Outer diameter of the cable is 5.2 mm instead of 5.8 mm as advertized. The overall thickness of the cable might be somewhat misleading as to the sturdyness, but it is fine as a cable for lamps and other devices with low energy consumption. As a lamp cable it was advertized, as such it is fine and will do the job. Recommended!
