I have their 13in grayscale e-ink device. I assume the underlying tech is similar. What they carefully filter out is the significant ghosting of the device that builds up immediately and needs to be cleared with a button on the monitor. The contrast is also poor and blends with ghosted content so you need more time to tell what’s real or junk pixels. The front light on the device is still required in most lighting situations unless you are in sunlight. Glare from non overhead lighting is very bad and worsened by the lack of a backlight. Content on significant portions of the page will flicker as you move your mouse and corrupt content already displayed unless you press the clear button. Content will flicker on many settings even without any movement. Even on the lowest refresh rate the device is still not really usable. I originally bought this to help with eye strain, but the poor visibility of content, flickering, and clearing action make it substantially worse than a regular monitor.

Edit: I’d also add that the device emits a coil whine when the display is updating like when moving mouse. Its audible enough to hear over my wall AC unit.

Just wanted to point out as a alternative datapoint thay i havr both 13: and 25" greyscale. And 25 is a much better experience. 13" is just to small. Im happy with 25" and will buy this new with color. I do not have flicker, at least not like you. but you need strong lighting on the screen.

Very valuable feedback, thank you. Coil whine would drive me bananas. Username checks out.

To be noted that EPD displays are in general completely silent. This exception...

Of course, there's more to a monitor than just the display. It could be the power supply, driver board, etc. that's the cause for coil whine. I've had it on one laptop that I owned; whenever there was I/O with the SSD I'd get a little bit of whine.
