TLDR: Read the pros and cons at the end... I probably havent seriously read a single book in the past 6 years. Even throughout college, I always wormed my way around reading the textbooks and class material. For me, there have always been 2 issues with books: One, they are cumbersome to carry around; two, they are overwhelming to think about. The XTEINK X4 solves both of these problems for me. The device is so small and slim (literally smaller than your hand), that putting it in your pocket adds no baggage at all. I can bring this thing anywhere, and read anywhere. Standing at a crosswalk, waiting for the walk signal? Read a quick paragraph on the X4. Sitting at work eating lunch? Bring out the X4. Hopping on the toilet and dont want to stare at the floor for the next 5-10 minutes? X4. On top of the portability, the size has a second advantage: it splits the page into digestable chunks. Gone are the days of tracking down which paragraph you left off on 2 hours ago. The device displays only a handful of sentences, so picking up where you left off is a cinch. Reading non-entertainment content (such as self help and textbooks) is more approachable too. I no longer feel overwhelmed by the sheer thickness of the book, or the length of the chapters. I can just take tiny bites, one at a time. Separate to how this device changes the reading experience, I really appreciate the fact that this device is "hackable". Unlike a device that rhymes with "jamazon bindle", XTEINK allows the community to develop custom software/firmware for the device. If you buy this item, I'd highly recommend looking for "Crosspoint Reader" on github. It really makes the device awesome to use. With all that said, here are the pros and cons of this device as I have experienced them: Pros: - Extremely portable (can even magnetically attach to some larger phones) - No subscriptions, No ads - "Hackable" - Bring your own ePub books - No touchscreen; physical buttons (gone are the days of accidentally swiping) - USB-C Port (no neeed for a new cable) - Expandable storage via micro-sd card. (You are not locked in to paying for an entirely new device if you run out of storage. - Tiny size makes tackling books feel easy. - Comes with a microsd card AND a microsd to USB-A adapter - Comes with a basic screen protector (Its glossy, so I opted to not use it) - Lanyard/wrist strap hole, if you think you need it. (Does not come with a lanyard). - Buttons are reprogrammable (to an extent) Cons: - Tiny size. If you are an avid reader, you might enjoy being able to read more words at once. - Limited accessory ecosystem. There are very few options for cases, screen protectors, and folios out there. (Check the official XTEINK website, since they have some items not listed on amazon.) - Included instructions are unclear. (You might need to look up some tutorials) - Does not include a USB-C cable. (But you probably already have one.. hopefully). - It can be unclear what the buttons do. (You'll learn very quickly, but it isnt obvious).

This _was_ an incredibly cool little device. I own two of them. As plenty of other people reviewing it have noted, the main draw is that there's a very very good third-party firmware, Crosspoint, that allows for added features and just an all around better user experience. As of the latest models, XTEINK has started to lock down the firmware to prevent users from installing Crosspoint. So, if you're reading these reviews, beware: the thing that a lot of people bought this for is going away soon. I hope XTEINK rethinks this decision, but until then: if you buy this, you'll be stuck with a different (and worse) product than what the reviews here are talking about. Shame on XTEINK for the bait-and-switch.

I bought this mostly as a curiosity, but I’ve ended up liking it more than expected. The size is the big win: it fits neatly on the back of my phone, so it’s easy to keep with me without carrying a full-size e-reader around. For quick reading breaks, travel, or just having a book available without pulling out another big device, it’s genuinely convenient. The screen is also very crisp. Text looks sharp and easy to read, and the e-paper display gives it that nice low-distraction feel compared with reading on a phone screen. The physical page-turn buttons work well and are easy enough to get used to. My only real wish is that it had a touchscreen. That would make navigation feel a little more natural, especially when browsing books and system menus. That said, the controls are simple enough that it’s not a dealbreaker. Overall, this is a neat little e-reader if you want something extremely portable, distraction-free, and easy to keep with you. It’s not trying to replace a larger Kindle-style reader, but for what it is, it works really well.

This is a fantastic minimalist e-reader device. After a bit of research, and installing the Crosspoint OS, I found myself actually reading longer then I normally do. I really do not like reading on my mobile phone. I do have several e-reader devices from other brands, but I really like the compact size of this one, and no ads or cluttered home screen with a store front promoting titles you are not interested in. The screen is sharp and clear in the light. I did 3d print up a couple of cases for it, plus an adapter that I can use with a book light for reading when in low light or in the dark. For myself, this is perfect. It's compact size makes it easy to slip into a pocket. And it does have a magnetic back for attaching to the back of your mobile phone device. After reading on it for about four hours, the power was only down to 95% so the battery life is really good. It does weigh a bit more then you would expect for it's size, but it is a metal case, not plastic. It functions exactly you expect. Simple reading.
