“I really like this keyboard, particularly due to its ISO PT layout. For the next iteration, I suggest using a higher-quality plastic, as the keycaps feel a bit cheap. I would easily pay 20/30 EUR more if the keyboard felt more premium.”
“I bought this keyboard from Amazon and I thought I love it. A little over a year later (15ish months) the keyboard starts glitching like the shift key is stuck and would randomly type in ALL CAPS and add weird punctuations. The keyboard made my…”

“This keyboard is perfect for me. Combined with the side-scrolling mouse I purchased, it does everything I need it to do, and is extremely comfortable to use all day.”
“My biggest issue is easily that they advertise these products as being Linux compatible, but as a recent convert, I wasn't aware how often companies will claim that, but then offer little or no support for actual functionality. When trying to flash updated…”

Keychron B1 Pro vs K15 Max: your questions
The Keychron B1 Pro is listed with an 800mAh battery and the manufacturer claims up to 1200 hours of use. The K15 Max Alice has a larger 2000mAh battery, but no specific runtime claim is provided in its description. The K15 Max likely offers longer life per charge due to its larger capacity.
No. The Keychron B1 Pro is not listed as hot-swappable in its specifications or description. Switches are soldered to the PCB and cannot be changed without desoldering equipment.
Yes. Both the Keychron B1 Pro and K15 Max Alice list Mac/Win support. The K15 Max description specifically notes it offers a Mac layout and keymaps can be configured for both operating systems using the Keychron Launcher.
The Alice layout, used on the K15 Max, is an ergonomic design that splits the main key columns and angles them to better align with natural hand positioning. The B1 Pro uses a standard, non-split low-profile layout. The Alice layout aims to reduce strain but requires an adjustment period.
Yes. Both the Keychron B1 Pro and the Keychron K15 Max Alice include USB-C connectivity for wired operation and charging.
The Keychron B1 Pro is more portable. It weighs 425g compared to the K15 Max's 700g, and it is narrower (296mm vs 370mm). Its lighter weight and smaller footprint make it easier to pack and carry.
Yes. According to the Keychron product description, the K15 Max Alice features advanced IXPE acoustic foam and resilient latex foam inside the case to dampen sound and enhance typing feel.
Yes, but through a different method. The B1 Pro description states it can be programmed using the Keychron Launcher web app for key remapping and macros. The K15 Max supports both the Launcher and the more advanced, open-source QMK firmware.
The K15 Max has RGB or white backlighting, but its keycaps are described as "non-shine-through PBT material." This means the light will shine around the keys, not through the legends, which may limit legend visibility in the dark.
The Keychron B1 Pro is a simpler, more affordable introduction with standard key placement. The K15 Max Alice, while feature-rich, combines the learning curve of a mechanical keyboard with the unique Alice layout, which might be overwhelming for a complete beginner.
Both keyboards support triple-mode connectivity: 2.4 GHz via a USB dongle, Bluetooth, and wired USB-C. The B1 Pro description mentions Bluetooth 5.2, while the K15 Max mentions Bluetooth 5.1.
