The software is buggy
The firmware doesn't work correctly/is buggy. - Switching layers doesn't work correctly on the Q3 Max. There is only one specific version of how to switch layers. Other options, provided by their own software and also by VIA, don't work. I only figured it out after resetting the device. - NKRO is sending multiple button presses on Q3 Max (example: qfhfeherziirwzzitwtuwtuiuh = actual input of 10 keys at the same time, which should register every key only once). 6KRO works, though. That's enough for me/most people, but Keychron claims to support NKRO (N = as many buttons as I want), which is a lie. - The Q0 Max Numpad's layers don't work correctly. You can use them, but you need to carefully disable the previous layer before activating another layer. Otherwise, the software gets stuck in a weird configuration where every layer is activated and none at the same time. - Q0 Max + Q3 Max = one full keyboard. However, they don't work together properly. Alt codes only work 50% of the time. Layers cannot be switched across keyboards and they also can't connect with each other's 2.4 GHz adapter. VIA doesn't work for either of the devices out of the box. You need to mess with JSON files to get this to work. It's not a big deal, but it's annoying. The reason for this is that Keychron doesn't care to register their devices at VIA. - Firmware version is still 1.0.0. There is no firmware update since the release, which shows that Keychron doesn't care. - Bluetooth doesn't work for gaming, as it seems to have connection issues. Buttons are not always registered (99% are, but that 1% is annoying for a >200 Euro keyboard). Other Bluetooth devices in my house, don't show this issue. Bluetooth isn't a good connection for input devices, but I encountered this issue very quickly, which is a red flag for me. Also, the Battery is much faster drained when it operates on Bluetooth mode. Apart from software issues, there are also other downsides: - No feet to raise your keyboard. - No adapter notch/holder. (So annoying!) - No off-switch. The Keyboards stay on until they eventually fall asleep. - Q0 Max has no battery indicator. While connected via 2.4 GHz, there is no way to check your device's battery. (Windows only reads for Bluetooth or USB connected devices.) Other brands show the battery in their software (e.g. Razer), the Q3 Max offers a battery check feature that works with LEDs, which hasn't been implemented into Q0 Max. - The connection switch and Mac/Windows switch are as cheap as they can get. They don't match the "premium" appearance at all. Switching between 2.4 GHz and USB is very tricky. I suppose this is what this keyboard will die from. If it is broken, you need to solder a 3-pin switch on a PCB. That's not that easily done with a regular soldering iron. Again, Keychron doesn't care. - I can also confirm these support issues others complained about. They didn't even reply after 3 emails, when I was asking for help. I'm done with Keychron. Hardware is not thought through, software is buggy, and support doesn't care about my issues.
