Well, I bought the device purely for its screen and for its paper-like reading function. I was looking for an e-reader that would be small (the size of a mobile phone) so I could easily take it with me and have Android software on top because I wanted various applications and not just the Kindle. I only found the Boox Palma but I wasn't going to pay 450€ for an e-reader even at gunpoint, so I got the TCL. For the function I want it for, it is more than perfect, reading for hours without straining my eyes, I have even switched it to black and white for even greater comfort. The Kindle app as well as all the others run flawlessly and I have seen a tremendous difference in my eyes and in the headaches I used to get from reading on the screen of my regular mobile phone.

This specific phone is definitely not for everyone. The basic category of consumers who will buy it must love Epaper readers/kindle, etc. Its unique technology makes it stand out, but don't expect to see amazing screen resolution or vibrant colors, super brightness, etc.
The device is ideal for those who spend a lot of time on their mobile and read articles, eBooks, etc.
Otherwise, it is a decent device for its price, with good battery life and generally good performance for everyday simple use!
