It is by far the most robust Keyboard I own and I have many! Keychron is renowned for its incredibly constructed Premium Keyboards and for its amazing VFM Budget options. This particular one is in the Premium category and it shows from its price. It is made of 6063 aluminum throughout the Case, quite thick Double-shot PBT Keycaps (OSA Profile), supports QMK / VIA, is Bluetooth, 2.4GHz Wireless, and Wired. It supports MAC, Windows, iOS, and Android. It comes with extra Keycaps to customize the Layout according to where you will use it, is 75%, and weighs 1.7 kg due to its metal and sturdy construction. It has a Knob, usually used as Media Buttons and RGB. Its Switches are Hall Effect from Gateron, meaning they work magnetically and this particular category of Switches is considered the best for Gaming. Many companies have made HE Keyboards on the market, at various Budgets, but none were at the level of Wooting until the release of the Q1 HE. The main difference was always the Firmware of the Keyboards that added extra Delay, however, Keychron managed to compete with Wooting's keyboards, both in performance and Features, and surpass it in build quality and VFM. One downside that unfortunately exists in most fully metal keyboards is that it does not have built-in height adjustment (the so-called "feet") but sits at a 5.2-degree angle and has four small round rubber feet on the back to prevent slipping while also providing extra height for more comfortable use. If you were used to "feet," it will take you a little time to get used to it. It has a 1000Hz Polling Rate in Wireless and Wired, and its battery is 4,000mAh. Personally, I was disappointed in the first days of use because sometimes I noticed that some keys were not registering when I pressed them, but it was fixed with a Firmware Update. Similarly, I had a problem with the Wooting 60HE where some keys would completely freeze until I unplugged/plugged the cable, and it was also fixed with a Firmware Update. It does not come with Software, but it has a Webapp that you open through a Browser, instantly finds the keyboard, you configure it, saves what you changed in the Keyboard's memory, and you're done. You don't have extra Bloatware on your PC. I find it excellent so far, after months of daily use. I have many HE Keyboards, from Wooting to Random Chinese companies, as well as classic "traditional" Keyboards, Custom or not. This one, I don't think will leave my desk anytime soon. An extra feature is that the Switches are Hotswappable, meaning you can either change them with others or if one breaks, you can easily replace it. However, in the case of completely changing the Switches to other models, you have the limitation of the type of Switches, so you have very few options. I wish Keychron would also release a cheaper and plastic HE Keyboard, to make its technology more accessible to the world. Because like it or not, as much as I like the Keyboard, I wouldn't easily recommend someone to buy something so expensive.
