If anyone's looking for a case, I just bought this one (genuine leather):
https://www.amazon.com/gp/product/B08CVKF6NJIt's intended for the iPhone 6+ so it's a little too deep but the width and thickness are perfect. A small piece of polystyrene at the bottom makes it perfect.
It isn't expensive: around £11, 11 and $14.
Just a few thoughts after a couple of months using this.
GOOD:
- It's small, so it's easy to carry around
- Powers up very quickly (about 3 seconds)
- It handles large files well (I have several "complete works of..." from Delphi Classics, and no problems with them)
- Plenty of memory for books
- Recognises books in subdirectories
NOT SO GOOD:
- Battery life: the battery drains very quickly even in sleep mode
- Doesn't handle grouping books into sets or categories
SUGGESTIONS:
- Battery life: as it powers on quickly, I tend to switch it off completely instead of putting it in sleep mode
- Book collections: create a subdirectory and place the books in it. To sort the books into order, add a number at the start of the name. Then use the file browser to open the book.
On the whole, I am very happy with the reader. Although it could be improved, I certainly don't regret buying it.
