After a year of use, I add a review of this wonderful book. A kind of iPhone among e-books, very autonomous, moisture resistant and with good soft backlighting. Moisture resistance was a separate requirement for me, I like to read while lying in the bathroom, and you can take it to the beach with you. Unfortunately, it does not support the popular fb2 format in 2022, but it's not a problem to recode to mobile, otherwise it's a great device!
