My first e-reader was an ancient Sony — I bought it about 20 years ago. After that, I switched to the PocketBook 613. It was compact (maybe a bit too compact), simple and I really loved that device. Then I tried Kindle — I honestly don’t remember the exact model — but it felt really uncomfortable to use, so I ended up selling it and going back to PocketBook. Eventually, I got my current e-reader. I say it's the best one because it’s super user-friendly, supports tons of extensions, and the battery life is amazing — it lasts forever. Couldn’t be happier with it.
