The Model O Wireless is exactly what it claims to be: a Model O, just wireless. Quite remarkably, Glorious managed to bring the Model O Wireless down to a weight of just 69 g, which is virtually identical to its wired sibling. At the same time, no compromises have been made in regard to build quality, which is flawless on my copy. I didn't experience any creaking, flexing, or rattling, and all buttons as well as the scroll wheel were firm and satisfying to use. The mouse feet provide excellent glide, and the materials are just as grippy as on the wired Model O. As far as battery life goes, Glorious promises up to 71 hours with illumination disabled, and from what I can tell, this is at least within the realm of possibility: After eleven hours of continuous use without illumination enabled, I didn't even get to see the 80% charge mark. What impressed me even more was how fast the charging was. Thanks to the USB Type-C connector, charging the little that was missing took less than five minutes. Coupled with the incredibly flexible cable that rivals many regular wired cables in terms of flexibility, Glorious really created a seamless experience with the Model O Wireless. The combination of above average battery life and the fast-charging capability also makes enabling the RGB lighting worthwhile, which is just as nice looking as on the wired Model O.

At the heart of a wireless mouse lies its wireless performance. For the Model O Wireless, Glorious partnered up with PixArt to create their "BAMF" sensor, which I believe to be based on PixArt's latest wireless flagship sensor, the PAW3370. Performance is great pretty much across the board. Recently, there have been reports about supposed angle snapping on the BAMF, but I was unable to find any evidence that corroborates such claims. As for motion delay, results are generally good, although there's a small caveat. Similarly to many 3335 implementations, motion delay isn't consistent across the entire motion. Basically, the sensor needs some time (roughly 100 ms) to "switch gears," so to speak, until it reaches its lowest-latency mode. At the onset of motion, latency is roughly 5 ms, but once in motion, latency is almost on par with Logitech or Razer in wireless mode, sitting at roughly 2–2.5 ms in total. Having said that, I was also informed by Glorious that their internal testing showed lower numbers. Glorious' setup involves a USB analyzer hooked up to the MCU and triggering the MCU motion pin, so it greatly differs from mine. Although I'm confident in my testing, it's certainly possible that I'm wrong here. In any case, we're talking about margins here, and the fact that we need to rely on such sophisticated empirical testing to determine the difference in motion latency should tell you that it's low enough to where it's difficult to notice for the average human's sensory capabilities. Furthermore, there is some CPI deviation, but since the BAMF allows for CPI adjustment in increments of 10, correcting any deviation in the software is quite easily done.

Speaking of which, Glorious developed an entirely new software called Glorious Core for the Model O Wireless. Eventually, Core is supposed to support all future Glorious products—older Glorious mice still rely on the old software, though. In terms of aesthetics and usability, Core is indeed much improved compared to the old software, albeit at a higher resource cost. Even though slightly buggy at release, subsequent updates have been successful in ironing out most bugs. In one of those updates Glorious also added the ability to lower debounce time to 0 ms, which decreases the already impressively low click latency even further.

Overall, I really enjoyed using the Model O Wireless. The low weight, great handling, and appreciable wireless performance, coupled with ease of use afforded by the lack of cable drag, made the Model O Wireless a joy to use in games. The Logitech G Pro Wireless and Razer Viper Ultimate come out slightly on top on paper, but I'm sure most people would be hard-pressed to notice any difference. And what's more important, the Model O Wireless retails for just $79.99, which is much better value than the $150 the G Pro Wireless and Viper Ultimate go for. Accordingly, the Model O Wireless gets our Editor's Choice and Budget awards from me.
