Hi all,
Thanks to the thread about the best cover for Nova Pro
now closed, I could find that dimensions with Ipad Mini 1,2,3 are similar.
For me, the original Boox cover didn't fit the reader (and is really expensive).
So I tried the following cover called
Atic Apple Ipad Mini ZJ case.
I bought this cover on Amazon Japan but it seems it can be found under another brand name on Amazon com, for example
Moko case Fit iPad Mini 3/2/1.
The USB port at the bottom can be reached easily, the magnet doesn't interfere when taking notes and there is a pen holder on the side.
The power button is hidden on the upper side, but for me it doesn't matter because sleep mode is active when the cover is closed and I never power off my reader.
The weight may be a little bit heavy for people who read during a long period of time.
And it is not so much expensive (9~10€)
I attach some pictures.
