Rapid trigger support was praised for responsiveness and tuning, though one reviewer framed it as most useful for niche gaming use cases.

Rapid trigger was repeatedly praised as useful for gaming, competitive advantage, and quick key deactivation.

Size and form factor were praised by full-size users and stationary setups, but the same size contributes to poor portability.

The 75% form factor was considered usable and not overly crowded, with enough keys for most needs outside a numpad.

Portability was the most consistent drawback, with multiple reviewers warning that the keyboard is too heavy to carry around easily.

Portability was a weakness because reviewers pointed to the board's weight, legs, and lack of Bluetooth for travel use.

Customization was repeatedly praised across actuation settings, key mapping, macros, RGB, and per-key commands.

Customization was praised for Hall-effect tuning, broad feature access, and the number of available controls.

Durability was supported by the rigid metal construction and comments that the keyboard felt built to last.

One review expected the keyboard to withstand years of use.

Switch options were the clearest customization weakness because reviewers repeatedly criticized the limited Hall Effect switch compatibility.

Switch choice was a limitation: reviewers noted Hall-effect switches are restricted to linears and wished for more stock options.
