You did not state in your original post that you were using a 2 inch prism erector.

Your friends may laugh, but the ability to reach infinity depends on ones eyes dioptre correction, if needed.
And also the strength of any glasses used. I.e. distance glasses or reading glasses etc.
If the optical instrument doesn't have enough travel, infinity views may not be reached for all users eyes.

Binoculars have to be specially adapted by moving the objectives to allow, especially severely myopic users, to reach infinity.

Camera viewfinders need correction dioptres for different users eyes, either inbuilt or accessory dioptres.
The viewfinders are typically set at about minus 1 dioptre.

I did show three diagonals ALL 2" so it was to be assumed that the other would be 2" also.......... sorry ...

Nothing that has anything to do with the product not being able to focus, this is the persons inability..................
