This class feature seemed to me to be dead-on-arrival when published.
It's unclear exactly which items originally presented in the DMG that this feature was intended to work with.
Exactly which items in the DMG are made usable by a level 13 Thief when granted the Use Magic Device class feature?
Of those items, which of them are meaningfully useful to a creature that doesn't otherwise meet those requirements?
(For example: Pearl of Power does nothing for a Thief even if they can ignore the class requirement of "spellcaster", so it is not meaningfully useful.)
Extending this question to all published works would be too vast of a question, but limiting it to originally published materials should be a reasonable task.
