What owners describe holding up is the whole device: screen, hardware and software, over three years of heavy daily writing in the most detailed account. Among a collector who has owned and sold many Boox tablets since mid-2024, none of the tablet-sized models broke; the single failure was cracked outer glass on a small pocket model, caused by the owner rather than the device, with the screen underneath still working.
We have to be plain that this is a thin record. Only three separate owners raised durability at all, and only one of them was speaking directly about the Tab Ultra C over a multi-year stretch. One account concerns a Pocketbook device, not a Boox, and another covers the Pro variant among many others. There are too few accounts to judge how this model holds up across owners, and no reports yet of what breaks on it or how people deal with it when it does.
