Akko Silver Pro

Yes. With roughly 1.00mm of pre-travel it actuates noticeably earlier than a standard 2.0mm linear, which makes it well suited to fast typing and gaming where a short trigger point matters.

It is a light switch: about 40g at actuation and roughly 50g at bottom-out, so it stays gentle through the keystroke and never feels fatiguing.

Not for most people. It ships factory lubed and feels smooth out of the box; a light hand-lube only sharpens an already clean stroke if you enjoy the work.
