“Genuinely happy with the keyboard. Had a low-profile one from another brand that has been used for 12+ years, and it degraded over time. This K5 feels very good. Still have to get used to the distance between the "primary," arrows, and numpad blocks, but…”
“Got this keyboard so I could keep my K5 Pro at work and this one at home. Both are the RGB version with brown switches, the K5v2 is quieter than the Pro and just as good to use. It also reports battery state over Bluetooth, which is a nice QoL improvement…”
