This has truly been a gamechanger for my reading. It is convenient, and the fact that it has a backlight has truly made it the best pocket rreader.

Love it! The touchscreen makes it easier to navigate through the menu’s and the front light is a game changer for late night reading sessions

Love this little device, I've always had issues with getting to read books and this has actually helped me a lot. X4 pro has a lot of features that kept me from buying one of these little devices.
One con however is the constant worry of damaging the screen. After hearing multiple stories on how everyone ended up damaging the screen...im really careful with mine and end up not taking it outside, especially since I paid 100$ for it. Otherwise I extremely reccomend this little guy to anyone who's had trouble getting to read or finish a book

The Xteink X4 Pro is the perfect complement to my 11-inch e-reader. Its form factor is very appealing, and the design impresses with its excellent ergonomics. The touchscreen functionality and backlight are exactly the features I had been missing. Thanks to the alternative Crosspoint firmware—and the ease of switching back to the original software—the device offers great flexibility. File transfer via the browser is also extremely convenient.

Great device but the display is not as sharp like the x3‘s display.

Ich bin wirklich sehr zufrieden mit dem X4 Pro. Das Gerät ist super handlich und einfach zu bedienen. Es ist ideal für unterwegs und ist genau die Ergänzung in meinem Bücherregal, die mir im Alltag gefehlt hat. Mir gefällt neben den Format besonders das beleuchtete Display und die Möglichkeit sowohl Tasten als auch Touch Display zu haben.
Des Weiteren hat das Überspielen einer anderen Firmware sehr einfach funktioniert, wodurch ich meinen X4 Pro noch mehr auf meine Bedürfnisse anpassen konnte.

Auch der Versand aus Übersee hat wunderbar funktioniert und das Paket war innerhalb von 9 Tagen (7 Werktagen) da.

After waiting a month for my Xteink X4 PRO, I was deeply disappointed to discover dust/debris trapped inside the display right out of the box. To make matters worse, despite support reading my inquiry email, they haven't provided any follow-up or guidance regarding a replacement. It is truly a shame because the device itself would have been great if not for the defect, but the customer service experience has been very disappointing.

I read 5 books in 3 weeks and my doomscrolling time went practically to zero. Native software could be more friendly but loading much better community-made OS is easy-peasy. I don’t remember when last time I bought a gadget changing my life for better - but XTEINK is a such gadget for sure.

Huge upgrade from X4 but the front light of my device flickers. I tried different settings but it is still the same even when the front light is turned off, so I think my unit is defective. I’ve checked with other users who has the same unit and they told me that their unit is working well and no flickers. I emailed their support but haven’t heard from them. :( So pricey so it’s really sad to receive a defective unit and no support was given.

Shipping was reasonably fast and in line with guidance on website. Unfortunately, shipper crushed the package and my device arrived broken 😞

Hi Jennifer, we're very sorry to hear about the damaged device. Please contact our customer service so we can assist you with a replacement or refund. Thank you for your understanding.

Wallet size or smaller, comes with enough storage for a good library of books and PDF, Actively being improved, and with each update it gets better and better. Magnetic charger can be finicky, but I’ll take a backlight all day long over previous hardware versions.

I’m excited to get to modding!

I finished a book in two days reaching for my Xteink X4 Pro rather than doom scrolling. This thing could be a game changer.

great product, I really love it, the light is a gamechanger. touchscreen is very good too, but not necessary in that kind of device. battery life is something you just don't have to worry about.

The ereader is now leaps and bounds better than the original X4. Front light is a welcome addition! Touch is convenient and familiar for phone users. It also accepts all epub files I loaded through xteink app, even the larger sized ones. Overall very nifty device to be carrying about during travels. Love it!

Exactly what I wanted! The X4 pro is the perfect eReader for me now that it has a front light and touch screen which makes operations much easier for my failing hands over my previous X3 device. Only thing I wish it had is a USB C port instead of pogo as the included adapter isn't as stable as the included cable with the X3.

Amazing little device! I can read at night and find this being my go-to as opposed to my Kindle.
