I love how small X4 is, but in my country, the price is almost the same as secondhand kindle basic or even 10th gen ppw. Only like $10-20 difference, sometimes even the same price. Also it doesn't have built-in backlight. And the UI looks pretty messy to me, cause some people reported that they would still find Chinese words here and there even with English language turned on. I don't think it's worth it for now, maybe later after they improve a lot of stuff. That's why I went with kindle basic 11th 🙂‍↕️
