I gave up on my Kobo Clara 2 when it would become completely unresponsive. Not saying all Kobos are bad!

I ended up getting a second-hand Tolino e-Reader in Germany for about €50 with a backlight. I have been able to import all of my Kobo ebooks there and have no issues so far!

Bottom line - unless you’re really looking for the “best” have a look at older gen second hand
