Boox Tab Ultra C

Owners use the Tab Ultra C for serious writing and reading, with some lag in apps like Kindle; one relied on it through three years of essays, exams and a thesis.

What keeps coming up

One owner wrote every essay, exam and thesis of a degree on the Tab Ultra C and, three years in, reports no hardware or software problems. Durability accounts lean positive so far, but there are too few of them to call it settled praise.

What keeps coming up against it

One owner finds the Kindle app laggy on the device, and it can't turn off the page-turn animation. Another says e-ink tablets in general are still slow. Performance accounts lean negative, but there are too few to call it a settled complaint, and one secondhand buyer says it runs very well.

What it is

The Boox Tab Ultra C line is made up of 10.3-inch color e-ink tablets that run Android, with a pen for notes and a camera on the back. Boox's store lists two models: the original Tab Ultra C and the newer Tab Ultra C Pro. Both show as sold out on the US store right now. The line is for people who want to read, mark up documents, take handwritten notes and run apps on a screen that is easier on the eyes than a regular tablet.

Specs

Several models, specs differ.

What the specs mean

The Pro is the upgraded version. Boox says its 2.8GHz chip is about 13% faster than the Tab Ultra C's and its downloads are over 5 times faster. It has 6GB of memory instead of 4GB, with 128GB of storage, and it runs Android 12. The Pro also adds Boox Super Refresh, which makes the screen update more smoothly, and it works with Boox's magnetic keyboard with a trackpad. Its body is 6.6mm thick and weighs about 450g.

Life with it

What lasts for the most committed owner is the work it handles: years of long-form writing and study done on one e-ink tablet, alongside a separate larger reader for multi-column articles. One owner bought a used unit cheaply and found it ran very well, even though they couldn't find any custom software images for it.

What owners adjust to is speed. One owner says e-ink tablets are still slow and limited enough that they don't know anyone who uses one as their main device. They are holding off on upgrading until the screen technology changes. Another has learned to live with some lag in the Kindle app and with a page-turn animation that can't be switched off.

Reliability & repairs

The clearest long-term account is a good one. After three years of heavy academic use, one owner reports no hardware or software faults. Another owner who has gone through many Boox devices, including the related Tab Ultra C Pro, says only a different model ever broke on them. The performance gripes in these accounts are about how apps feel, not about things failing.

The long-term evidence for this exact tablet is thin. Only one account follows the Tab Ultra C itself over several years, and the cracked-edge story in the durability sample is about a different brand of reader, not this one. Because no breakages are described for the Tab Ultra C, there is nothing yet on what owners do when something goes wrong.

Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.

7 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
