Build Quality
The Keychron C1 is a tenkeyless (TKL) mechanical keyboard that offers a solid build quality despite its budget-friendly price point. The keyboard’s frame feels sturdy, with minimal flex, and the keys are very stable, providing a reliable typing experience. The keyboard doesn’t move when typing, which is a testament to its robust construction. However, some users have reported that keys with stabilizers, such as shift and return, are louder than non-stabilized keys. This issue might require some modifications, like filling the case with foam, to improve the sound quality.

Key Switches
The Keychron C1 offers a choice of Gateron Blue, Red, or Brown switches, catering to different typing preferences. The hot-swappable feature of the keyboard allows users to change switches without soldering, providing a high level of customization. This feature is particularly beneficial for users who want to experiment with different switch types or anticipate changing their preferences over time.

Keycap Material
The keycaps of the Keychron C1 are made of double-shot ABS material. While ABS keycaps are known for their smooth texture and shiny appearance, they may show oil shine from fingers over time. However, Keychron offers a variety of PBT and ABS replacement keycaps, allowing users to customize the look and feel of their keyboard.

Design
The Keychron C1 features a tenkeyless design, which means it lacks the right-side number pad found on full-size keyboards. This design choice makes the keyboard more compact, freeing up desk space and making it a practical choice for users with limited space or those who prefer a minimalist setup. The keyboard also includes LED indicator lights for Caps Lock and to show whether the keyboard is in Mac or Windows mode. The Keychron C1 is available in different versions, including models with white or RGB LED backlighting.

Price
The Keychron C1 is an affordable option for those looking to enter the world of mechanical keyboards without breaking the bank. Despite its budget-friendly price, the keyboard doesn’t compromise on quality or functionality, offering a consistent typing experience and a mature retro aesthetic. However, some features, like RGB backlighting or hot-swappable switches, may require a slightly higher investment.

In conclusion, the Keychron C1 is a solid entry-level mechanical keyboard that offers good value for money. Its sturdy build, customizable switches, and compact design make it a versatile choice for both beginners and experienced users. However, users may need to make some modifications or invest in higher-end models to achieve the best sound quality or additional features.
