I had the exact same experience with that model. The screen eventually cracked (I think I had it in a backpack that I was a bit too rough with). It was easy enough to replace the screen with one I found on AliExpress, but unfortunately the replacement then cracked a few weeks later. I don’t know whether it was because the replacement screen was poor quality or because once I had taken the device apart the screen was less protected, but I figured I wasn’t going to throw good money after bad. I ended up getting a second hand Kobo Aura on eBay which has served me well.

eReaders have gotten some new features like backlights but I don’t think the technology has fundamentally moved on all that much.
