Bought a couple of these for my colleagues at work, and the worked straight out of the packet.

I have tried different adaptaters before with no luck. This is works like a charm

Advertised as supporting 4k which implies 4k 60hz support. But only supports 4k 30hz. Not putting it on the site or the box is to hide the fact that its only HDMI 1.4 rather than 2.0 while still trying to pretend its good for next generation displays when its really not. It's fine for 1080p, but you should just buy something cheaper for that use case.

I received a replacement cable in January, the sound stopped working in March. I stopped using it for a while then connected it again yesterday. It worked fine, but today, no signal at all! There is no visible wear on it. I even tried a different HDMI cable with it. Still nothing.

I bought this product in February and it stopped working in September. There is no visible wear on it. I even tried a different HDMI cable with it. Still nothing.
