4.7

Across multiple reviews, the switches are described as tactile or smooth, with a satisfying pop and bouncy feel rather than a harsh or scratchy response.

switch options
Product 1: Logitech G915 Lightspeed
4.5

Multiple reviews note three switch choices—clicky, tactile, and linear—giving buyers real feel options instead of a one-switch lineup.

Product 2: Keychron Q3 HE
