Suggestions for buying new E-reader

Hi I need some suggestions for buying a new E-reader, because my tolinio vision 4 hd broke and their customer service is fucking craptastic. I read online about the e-ink mobius display and want to get a reader with that kind of display since on my old one the screen broke from laying on a flat surface

Thanks in advance

Edit: Size doesn't matter at the moment, I'm just gathering suggestions because I can't find them easily online
