Glorious Model O 2

The wired Glorious Model O 2 weighs under 60 grams, making it noticeably lighter than the original Model O, which came in around 67–69 grams. The weight reduction comes from a refined honeycomb shell design that maintains structural rigidity. The wireless version (Model O 2 Wireless) weighs slightly more at around 69 grams due to the battery.

The Model O 2 uses Glorious's BAMF 2.0 sensor, developed in partnership with PixArt, capable of up to 26,000 DPI with a polling rate of 1000Hz on the wired version. The wireless variant supports up to 4000Hz polling when used with the separate 4KHz dongle. This sensor competes directly with the Focus Pro 30K used in Razer mice like the Viper V3 Pro.

The Model O 2's low-profile ambidextrous shell with a subtle mid-back hump works well for claw and fingertip grip styles. Palm grippers with larger hands may find it too shallow compared to ergonomic mice like the Razer DeathAdder V3 Pro. The matte coating and side grips provide adequate purchase for most hand sizes.

The Model O 2 uses Glorious's pre-tuned GPFS (Glorious Purple Fusion Skates) 100% PTFE feet for smooth gliding. Unlike some enthusiast mice such as the Finalmouse Starlight, the switches are not hot-swappable without soldering. Glorious rates the mechanical switches at approximately 80 million clicks using their custom optical switches.
