The cable is reliable with good build quality and does not have interruptions. I bought 3 pieces for PCs and receivers like NOVA. When connected from PC to TV, it provides decent 4K image and automatically works at 60Hz in a specific port. If connected to another port, it outputs at 31Hz (this happens with all cables, not just this specific one from PC, while from Cosmote/Nova receivers or other satellite receivers except for 4K, it outputs at 50Hz in all HDMI ports). In other TVs, it only outputs in one port and distributes to all (depends on the TV types and their settings).

NOTE 1: Apart from the visual experience, it also depends on how each person perceives it (I'm not saying this, the technicians do). It may appear differently to me than to someone else. It may be perfect for me, but good or mediocre for someone else. There are many factors at play, not just the cables...
NOTE 2: The strange thing is that from the 30Hz splitters/switches, the 60Hz cable (input/output) works normally on the TV according to what the port shows us.
