Glorious's 66g wireless mouse swaps battery packs so it never has to plug in, but the feature mostly benefits esports players, and wireless tracking trails pricier rivals.

What we like
- Hot-swappable InfinitePlay battery packs mean you never plug in to charge, and the Guardian Battery keeps the mouse connected during a swap
- 66g shell feels light and solid, with no honeycomb holes
- Up to 8K polling through the included base, which doubles as the charging hub and shows battery, polling rate and DPI
- 30K DPI BAMF 3.0 sensor with 750 IPS tracking speed and 130M-click optical switches
- Priced at $99.99, it undercuts the flagship wireless mice it competes with
Could be better
- Not class-leading on weight: the Razer Viper V3 Pro and Logitech G Pro X Superlight 2 are both lighter
- Hands-on reviewers have found its wireless tracking less convincing than the best competitors
- The swap system adds complexity most desk users will never use
- Amazon buyers rate it a modest 3.6 from 66 ratings
Full Review
Build and Design
The Model O3 uses a solid shell rather than a perforated one, and it still weighs 66g. That’s light enough to feel quick and effortless in a claw or fingertip grip. It’s not the lightest mouse at this price, though. If weight is your top priority, the Logitech G Pro X Superlight 2 and the Razer Viper V3 Pro both sit lower.
A closed shell does mean fewer places for dust to get in, and it feels sturdy in the hand. The 130M-click optical switches should also outlast most mechanical alternatives.
The Battery System
This is the reason to buy the O3. Two battery packs live in the mouse and on the base. When one runs low, you pop it out and slot in the other. The Guardian Battery keeps the mouse powered during the swap, so you stay connected. Glorious quotes up to 130 hours of battery life.
For competitive players who can’t afford a mid-match charge, that’s a real advantage. For everyone else, it solves a problem you probably don’t have. A normal wireless mouse that you top up on a dock overnight will serve a typical desk setup just as well. If you want the simplest wireless experience, consider the Glorious Model O 2 Pro Wireless instead.
The base is useful in its own right. It supports up to 8K polling and shows battery charge, polling rate and DPI on its display.
Performance and Daily Use
The BAMF 3.0 sensor tops out at 30,000 DPI with 750 IPS tracking speed. That’s more than anyone needs for gaming or desk work. The catch is that some hands-on reviewers have found the wireless tracking less convincing than the best rivals at this level. Casual players won’t notice. Highly competitive players might.
For work, the light weight and comfortable shape make it easy to live with all day. Glorious’s CORE software currently supports Windows only, which matters if you use a Mac.
Who Should Buy This
Buy the Model O3 if you play competitively, hate downtime, and like the idea of swapping a battery instead of waiting on a charge. At $99.99, it’s a more affordable way into a premium-feeling wireless mouse.
Skip it if you just want the lightest, best-tracking wireless mouse. The Superlight 2 and Viper V3 Pro are lighter and more refined, though they cost more. Also skip it if you use macOS and want full software support, or if you don’t care about swapping batteries. You’d be paying for a feature you’d never use.
