How to choose REALFORCE

REALFORCE R2 is a keyboard that supports only wired connections.

Like HHKB, it uses the “capacitance non-contact ” input method, which is a mechanism that physically prevents “chattering” from occurring.

This time All models are bearing the “PFU Limited Edition” and have the same pressing pressure of “45g” as the HHKB. The pressure is the same as that of the HHKB.

The regular REALFORCE has a “30g” key feel, which is even lighter than the HHKB, but this time, as a collaborative product with PFU, it has the same typing feel as the HHKB.

If you want independent directional keys, don’t want to carry it around, and want a numeric keypad, this is a better choice than the HHKB above.

It is important to note that the keyboard cannot be used in conjunction with a Mac/Windows keyboard.

While HHKB can be used together regardless of the OS, REALFORCE cannot be used together basically because the key printing and layout differ depending on the model.
