The best thing I have ever bought. Literally solved all my problems with those electronic books I had and didn't know where to read them. It doesn't strain the eyes and even in the sun, it feels like reading a regular book. The battery lasts a long time and with continuous use, it lasts around 3 to 4 days. Maybe even a little longer. Also, an important thing is that if you forget it open, it automatically closes after a while. I recommend loading only files in Epub format as PDFs appear with very small letters and it makes reading difficult because you can't zoom in due to the nature of the file. That is its only negative aspect.

I love it. Slightly heavier than the previous Basic Kindle (add some extra weight for the case that I consider necessary*), but I didn't want to support Amazon.
The physical buttons are really convenient because I can simply turn the page with the hand that holds the device.
The shortcut capabilities are something magical, as well as those of the page settings, even in scanned books.
It is relatively slow, but we are talking about a device completely different from tablets/smartphones. It is intended for reading. This specific one also supports audiobooks (whose files are clearly larger than written ones).
Very disability-friendly for people with partial vision and hand mobility difficulties. There is also a text-to-speech function. For this, a speaker or Bluetooth headphones will be needed.
For anything else I discover, I will come back.

*necessary not only for drops, but also for water (even though it is a waterproof device), dust, and protection among other items inside a bag.

Excellent ebook reader. It has all the features for a must-have ebook reader. Small and convenient in size to take it wherever you want, waterproof, high-quality screen, warm light for even more comfortable reading at night, very good construction... overall, the new design and materials give a premium feel. Additionally, I will also mention the buttons that are very convenient.
