Much stronger than plastic connectors to avoid (a little more expensive but worth it) All metal, it is not going to break with the black tip it is plastic but just to give slack to the cable outlet. It can be dismantled completely by opening two (allowing reuse without breaking) by cons for the back one is at the beginning a little puzzled because montages instructions printed on the bag are rather obscure but found quickly by itself because it is not too complicated. The fasteners are easily welded, which is then covered with a small internal carrier protection plastic, placed in the metal tip that is closed and it moves. Only minor drawbacks, the whole is a bit heavier and bulkier than plastic and I wish I had a straight version and not angled.
