Top critical review
All four have now failed, one by one.

Update: I bought these less than 2 years ago, and one by one I have thrown them out when dropouts occurred with a variety of different equipment. I suspect these cables are just not up to spec. They are so much thinner than other hdmi cables. This has happened only a couple of times with a dozen or so different hdmi cables I have owned over many years so these are significantly worse than average. I now buy bluerigger and have not had issues.
I had occasional moments when the image would go to digital static then disappear, when I used one of these 6 foot cables to connect my Macbook Pro to an LG OLED 4k TV. It worked most of the time, but the dropouts would happen after about 10-20 minutes on average. I switched to another much thicker HDMI cable from another brand, and have not had the dropouts.
I suspect that the small diameter of these cables is a sign that they aren't quite up to spec for high bandwidth 4k connections. However I have had no problem using these cables for connecting my 4k Roku or 4k disc player, so most people probably won't run into the issue I did.
