Design and construction

One of the first things that catches your attention about the BOOX Go Color 7 is its compact design, with a thickness of just 6,4 mm and a weight of around 195 grams, making it an extremely portable device. This reader is comfortable to hold for long periods of reading without causing hand fatigue. Unlike other models made of aluminum, the casing is made of textured plastic, which improves grip and prevents the device from slipping easily. This rough paper-like finish is especially pleasant to the touch, and helps a lot with grip.
The front is dominated by its 7 inch, surrounded by relatively thin bezels, except on one of its sides, where it widens to facilitate grip without obstructing the screen and offers a pair of physical buttons for page turning and other functions, as they are customizable, allowing them to be adapted to continue reading or control other functions according to the user's preferences. This ergonomic design makes it suitable for reading in any orientation, as it also has a auto rotation sensor which adjusts the screen based on how you hold the device.
Splash resistance
Another notable aspect is its splash resistance, allowing the device to be used near water, such as in a pool or at the beach, without having to worry excessively about small accidental splashes. Although it is not a submersible device, this feature is useful for those looking to read in more relaxed environments without fear of some hazard ruining the device.
Display: Kaleido 3 color e-ink

One of the great innovations of this device is its Kaleido 3 color e-ink display. While traditional eReaders have primarily used black and white displays, the BOOX Go Color 7 offers the ability to display up to 4096 different colors. This capability makes it a great choice for those who enjoy reading comics, magazines, or any other content that includes color images, although it should be noted that the colors are not as vibrant as those you can see on an LCD or AMOLED screen. This is something we have already experienced on other color e-ink models, but the battery life that is achieved on these devices is well worth that small sacrifice in image quality.
La resolution of the screen is X, which offers a density of 300 ppi in black and white y 150 ppi in color. This ensures that text appears crisp and clear, while images and graphics feature sufficient detail for a pleasant reading experience. In addition, the screen is protected by a Onyx Glass crystal, which not only protects it from scratches, but also reduces glare, improving visibility when reading outdoors.
As we have already mentioned, electronic ink technology also allows lower energy consumption, as the screen only uses power when you change images or pages. This, combined with the adjustable front light, makes the device perfect for reading in low-light conditions or at night without damaging your eyesight. In addition, the BOOX Go Color 7 features various screen refresh modes, which allow the user to optimize the reading experience according to their needs. These modes range from the standard mode for reading books to faster options for web browsing or using multimedia applications, thus making the most of the battery.

From the notification bar, you can also quickly access functions for controlling brightness, color temperature, and Wi-Fi or Bluetooth connectivity.
The BOOX Go Color 7 not only lets you read books, but also comes with a range of pre-installed apps such as a web browser, music player, voice recorder and calendar, making it a multi-functional device suitable for both work and leisure. The downside is perhaps that the addition of Android modifies the classic e-book reader experience, as the device switches off after a certain time to reduce power consumption. This means you have to turn it back on and wait for the startup time every time you use the device again (provided the auto-off time has passed), which takes away from that classic e-book reading experience of immediately resuming reading.
Format compatibility
