Trade-offs

• The keyboard’s 98% layout lacks a dedicated numpad, which may be less ideal for users needing extensive numeric input.
• Battery capacity is 4000mAh, but actual wireless usage time is unknown from available data.
• Customization relies on a web-based driver, which may be less flexible or offline-accessible compared to traditional software.
• Switches are linear only, so users preferring tactile or clicky feedback will need to replace them.
