Frequently asked
Why is the Speed Silver good for gaming?
It pairs a light 40g spring with a very short 1.1mm pre-travel, so keys actuate almost the instant you press. That quick, low-effort response is ideal for fast in-game inputs.
Is the light actuation a downside for typing?
It can be. The short travel and light weight make accidental presses easy, so some people fit a heavier switch on the spacebar where they rest a thumb.
Does it need lube?
It is usable stock but ships a little dry. A thin lube on the rails smooths the glide and quiets the switch, especially on a resonant aluminum plate.
