Cons , different No backlight Switch type and software not stated on Keychron's page No review of this exact model found Wireless is Bluetooth only, at 90Hz polling; 1000Hz needs a USB-C cable No 2.4GHz option on the Pro; Keychron lists the Q1 Max for that Heavy for a 75% and not a board to carry around Tom's Guide heard a slightly hollow stock sound and occasional metallic pings Tall KSA keycaps raised mistype rates in Tom's Guide's typing test An r/Keychron owner report describes spacebar rattle from the stock stabilizers Tom's Guide called the $219 assembled price steep at review time (Nov 2024)
Research take , different A plain full-size slim board with thin evidence behind it. The B6 Pro reviews are the closest guide. A comfort-first 75% that suits long typing sessions better than gaming or travel. Reviewers rate the build and typing feel highly and mark it down for weight, price and a stock sound that can ping. If you want 2.4GHz or magnetic switches, compare the Q1 Max and Q1 HE before buying.
