What will you mostly use it for?
The K721 has the clearest edge for gaming that benefits from Hall effect switches, Rapid Trigger and high polling. The RT85 takes the other four categories on connection flexibility, screen and joystick controls, and broader mechanical-switch swapping. Travel is a mixed decision: the RT85 can run wirelessly, but the K721 is lighter. For buyers who want one board to move between tasks and devices, the RT85 offers more flexibility; for a wired gaming setup, the K721 is more specialized.
Pick the Redragon K721
- The K721 combines Hall effect magnetic switches with Rapid Trigger for repeated keystrokes without a full release.
- Its listed polling rate is 8000Hz, compared with 1000Hz for the RT85 in wired and 2.4GHz modes.
- The RT85 offers N-key rollover and wired or wireless play, but does not list Hall effect switches or Rapid Trigger.
