Thank you very much.
A521 Left, A471 Right.
Someone apparently said 521 was bad so I can't explain my results, but I have literally no issues. I even used a measuring tape and went behind a wall 17+ feet away, and I am still able to control Link and do everything flawlessly. Hope this helps.
I'm not sure what these are there for at all, but yeah that's the first conflicting number.
