I intend to use "either" instead of "any" in an essay. I was wondering if this is grammatically incorrect to say the following: "Users could press either buttons of their stylus"

instead of following: "Users could press either of the buttons ..." ?

    That's okay except that button is not plural. It would probably be better as " [...] either button on their stylus".

  • Also, I wouldn’t use either unless there were only two buttons. If there were more than two buttons, I’d say, “Users could press any button on their stylus"

Users could press either buttons ......

The sentence isn't correct.

You use the singular form of a countable noun in front of "either". If you want to use "of" after the either, you use the plural form of a noun. So you can say:

Users could press either button......

Users could press either of the buttons.....

Both the sentences have the same meaning.
