Choose the version for your desk
Each configuration identifies a complete keyboard version. Read the color, switch and layout details together before choosing; the choices shown in one label belong to that same version. Compare the product photographs with the selected label, especially when different finishes or keycap designs are offered. The price updates for the chosen configuration, so review the final selection in your cart before checkout.
Consider the space available on your desk and the key arrangement you use every day. A compact layout and a full-size layout place navigation keys differently, and only versions explicitly described as full-size include that arrangement. Check the stated connection methods against your computer and keep the appropriate cable or wireless receiver available when required. Switch and backlight choices vary by configuration; do not assume that an option offered on another model is included here.
The gallery presents the product from several views. Props and accessories shown beside a keyboard are not included unless the selected configuration or included-items description says so. Keep the complete SKU displayed with your choice for product-support enquiries. Published availability is captured for each configuration; exact supplier stock quantities are not provided.
