When choosing wiring terminal, must distinguish carefully:

First, look at the appearance, good product is like is a handicraft, which give a person cheerful and pleasing feelings;

Secondly, the selection of materials should be good, the insulation parts should be made of flame retardant engineering plastics and the conductive materials should not be made of iron. The most important is the thread processing. If the thread processing is not good and the torsional moment does not reach the standard, the function of wire will be lost.

There are four easy ways to test : visual (check apparence); amount of weight (if it is too light); using fire (flame retardant);try the torsion.
