Surprised that it is delivered in a platic bag, but after all ... Once plugged ... For shielded cable, OFC with quad shield is flexible (that is neither a string nor a wire) .The contacts (protected by caps) are 24K gold ...? The plugs are metal: it's your costaud.Attention taken if fragiles.Branchés (two two meters) to a 3D player to amp then to TV, dire.3D anything and everything that goes with it, all multichannel sound (except 9.1 cà has nothing to do), ARC ... Everything passes and pretty mal.Je have not tried Ethernet (I have no utility) it is a 4K .Résolution another story. Compared to my HDMI (two years old, which is compatible with 100% above 11 mm in diameter, 15m long for the projector and the three-digit price) "Cronos" seems to be a low cable / medium game.Pas at all! this is not the same material that is used. For me, the construction is excellent manufacturing and assembly exudes solidité.Donc price / quality deserves far five stars.The time prove me wrong or right. Very significant: the seller is contacted by intremédiaire of Amazone.Il is very professional and very friendly, which is rare these jours.Quant to Amazon, as dab, bravo.
