What will you mostly use it for?
The K708 Pro is the more suitable pick for gaming, programming, modding, and content creation because it is a complete keyboard with added controls and customization features. Office use depends on whether a dedicated calculator and number pad or a broader typing layout fits the workflow. The Retro18 is the more compact choice for adding numeric input away from a main keyboard. Neither product replaces the other's core role: one is a numpad, the other is a 75% keyboard.
Pick the Redragon K708 Pro
- The K708 Pro has a 75% layout with 81 keys, while the Retro18 is a numpad rather than a full keyboard.
- The K708 Pro specifies a 1000 Hz polling rate and RGB backlighting.
