But now to the product: For the price, I expect no high-end product. But: The plug unfortunately not even fulfill their basic function - namely a detachable electrical connection. Why: The plugs are made of a pin and made a - what I would call - the spring sleeve. The longitudinally slotted spring sleeve is intended to give a non-slip grip in a socket and make good electrical contact between plug and socket. This works well so far. But the contact between the pin and the sleeve is flawed. The sleeve is too large and is not so far as compressed when inserting the plug into a socket that there is a good electrical contact between pin and spring sleeve. Had the longitudinally slotted spring sleeve in scope one millimeter smaller, so the problem would be solved. This problem is not due to a too large bush !! I can only advise against the purchase. Flexible cables should be stuck with a ferrule in the connector, otherwise there is another problem - particularly with thinner cables.
