These cables are reliable, robust and cheap. Contrary to what one can read here and there about the problem of too rigid cables and son who break or dessoudent, these cables do not show any weakness. In addition, when switching on of the light, it is necessary to have a sufficient strength not to break the cable optical fiber inside. I use it with my tv and my samsung samsung sound bar and there is no problem. The HDMI cable is very correct. Personally, I see no difference between a cable says "professional" and 90 thereof. I think it would work for a movie studio but I'm not convinced ...
In other words, you can buy these cables eyes closed without breaking the bank.
PS: I have not had the opportunity to test the "ethernet" function hdmi cable so I do not comment on it.
