Questions about this item

How long do the UltraMag magnetic switches last before they need replacing?

The UltraMag switches use a full-POM construction with an enclosed base and anti-wobble dual-module floating structure, which are designed for high reliability and smooth keystrokes without mechanical wear points.

What limits performance during long gaming sessions with 8K polling active?

The keyboard transmits inputs at up to 8000 Hz with a lowest latency of 0.125 ms via the detachable USB-A to USB-C cable, maintaining consistent response under sustained use.

How much noise and heat does the keyboard produce when running all day?

The 2-layer noise dampening and full-POM silky magnetic switches deliver a crisp, Hi-Fi sound profile with minimal acoustic output, while the wired USB connection generates negligible heat during continuous operation.
