Our take, based on research
A plain full-size slim board with thin evidence behind it. The B6 Pro reviews are the closest guide.
Overview
The B5 Pro is the full-size member of the ultra-slim B-Pro line. Keychron's page lists a 100% layout with 112 keys, ABS keycaps, an 800 mAh battery rated at up to 300 hours, 1000Hz polling, tri-mode connectivity and no backlight. It weighs 623 g. Keychron's page does not say which switches or software it uses. WIRED reviewed the earlier full-size B6 Pro and found it comfortable, with a springy feel close to Logitech's MX Keys; that is a sibling reference, not a review of this board. Parka Blogs' review of the B3 Pro reports missing shortcuts on that 75% sibling.
