These cables are solidly built and don't appear to have had any issues over time. They seem like a lot for 2 10ft cables. Both are correct 2.1 cables as advertised and enable all video options between my Series X and the 4k TV. So there are definitely no complaints about their performance yet. Strangely, one of my cables was missing one of the small plastic connector covers, but that didn't matter. The only real potential downside I see with these cables is that they are quite thick making it difficult to bend the cables much near the connectors and difficult to plug into tight spots and can lead to hanging them over the TV (e.g. my pic.) Depending on your needs, your mileage may vary if that's an issue. Although it was ok for me.
