I bought an Aura One and it had quite few issues: battery drain (over night), phantom touches and the light sensor constantly adjusting the brightness. Also, it is not recognised by any of my Windows 10 devices.
I returned it for an exchange which had all the same issues plus the comfort light having a orange hue left and green hue right side of the screen (which the first unit did not have).
Turns out there's a firmware update to be released that is supposed to address the battery issue which has been delayed since Sep 26th. There seems ZERO quality control re hardware and software for a product that is sold at a premium price.
I just returned it for a refund and closed my Kobo account. Never again.
