My review of the KBDfans Roller V2, a ball-bearing linear switch engineered for low friction and almost no stem wobble. Specs, sound, feel and tuning.

Frequently asked
What do the ball bearings actually do?
The Roller uses ball bearings in the stem so contact with the housing shifts from face-to-face to point-to-point. That cuts friction on the keypress and clamps down hard on stem wobble — the headline feature here.
Should I swap the springs?
No. The V2 redesigned the leaf to quiet noise with the stock springs, and spring-swapping can reintroduce that noise. Leave the springs in place.
Are they good stock?
Yes. They come factory lubed and are smooth out of the bag. The ball-bearing design is doing the heavy lifting, so there is little to gain from a hand lube.
