Glorious Model D 2 and O 2 Pro Gaming Mice Review

Glorious specializes in high-quality computer gaming mice, keyboards and related accessories. While the company has quite a few flashy products with LED bling, Glorious also has some conservatively designed peripherals that wouldn’t look out of place in the average office. The glorious D2 Pro And O2 Pro Mice from the series are devices that do just that: provide gaming sizzle without the outward flash.

At first glance, there isn’t much difference between the Glorious Model D 2 Pro and the Model O 2 Pro, and even less difference between the 1K and 4K/8K versions of each model, and that would be largely true. However, if you look a little closer, there’s a lot to like about Glorious’ subtle, yet nuanced approach to its Pro Series mice.

Glorious Model D 2 and O 2 Pro – Designs and Aesthetics

Glorious gets surprisingly detailed with its individual Pro mouse offerings to the point where it’s hard to tell them apart. For the Pro series there is the Model D 2 Pro 1K Edition ($99.99), Model D 2 Pro 4K/8K edition ($129.99), Model O 2 Pro 1K Edition ($99.99), and Model O 2 Pro 4K/8K edition ($129.99).

The most noticeable difference between Model D 2 (aka Wireless Ultralight Esports Mouse) and Model O 2 (aka Wireless Ergonomic Esports Mouse) is the shape. Otherwise, functionality and software are virtually identical for the respective 1K and 4K/8K editions.

The Model D 2 Pro has a shape reminiscent of the classic Microsoft IntelliMouse or the more recent ones Logitech G703 LIGHTSPEED wireless gaming mouse, with a somewhat irregularly shaped bottom section sloping to the right. It is what would be considered a right-handed mouse, good for a palm or claw grip.

The Model O 2 Pro, on the other hand, has a slimmer and more symmetrical shape, with a design reminiscent of the Logitech G Pro X Superlight, just with a hint of more outward flare at the top and bottom. It is what would be considered an ambidextrous mouse, although the two buttons on the left are generally intended to be accessible with a right-hander’s thumb. This shape is not only suitable for a palm or claw grip like the D 2 Pro, but also for a fingertip grip, if that is your preference.

The designations 1K and 4K/8K simply refer to the maximum polling rate. A polling rate of 1K or 1000 Hz means the mouse position is updated every 1 millisecond, while 4K is every 1/4 millisecond and 8K is every 1/8 millisecond. In general, the higher the polling rate the better, although not every game is compatible and requires more resources from both the PC and mouse, reducing the latter’s battery life to less than half at 4K. If you want 8K, it won’t even work with the included 2.4GHz 4K wireless receiver, but instead you’ll need a wired use of the included Type-A to Type-C Paracord charging cable or something similar.

Glorious Model D 2 and O 2 Pro – Software and customization

Using either mouse is as simple as connecting the included 2.4GHz receiver, or, if you want to use the mouse wired, the included Type-A to Type-C Paracord charging cable or equivalent. Of course, the mouse must be fully charged before first use and you must remove the protective film from each of the four mouse legs (skates), but other than that you do not have to do anything for basic operation.

Glorious CORE is the unified software suite for the company’s Pro peripherals, including the D 2 and O 2, and allows you to unleash the full potential of the mouse, including firmware updates. This requires a computer running the 64-bit version of Windows 7 or later.

Once installed, the app will display an image of the connected mouse, as well as how the mouse is connected, battery life, and more. My Windows 11 Home desktop placed a Glorious CORE icon in the system tray, which allows you to open or close the app.

Three different Key Binding and Performance profiles can be set. By default, the key binding is set to Left Button, which is the left mouse button, Right Button, which is the right mouse button, Scroll Click, which is the scroll wheel, DPI Cycle Up, which is the small button below the scroll wheel, Forward, the first button on the left , and Back, the second button on the left.

Among other things, Performance lets you set one of four color-coded DPI stages, each of which corresponds to the LED coloring of the DPI indicator light under the mouse. Standard is yellow 400 DPI, blue 800 DPI, red 1600 DPI and green 3200 DPI. You can also configure several other settings, including Lift-off Distance, which is how far the mouse sensor must be from the mouse pad or other surface to stop tracking, Before Press Time, which adds debounce delay at the exact moment you mouse press button to minimize double presses, and more. There’s little about the mouse and its movement that can’t be fine-tuned with the app.

On the 1K versions of the mice, the polling rate can be set to 125 Hz, 250 Hz, 500 Hz or 1000 Hz. The 4K/8K versions add options of 2000 Hz, 4000 Hz and 8000 Hz, the latter of which is only possible when using the mouse wired.

Battery life maxes out at 80 hours, which is a bit low for mice with such low light, but more understandable considering the featherweight weights. Battery life can be checked in wireless mode by pressing and holding the DPI button for three seconds and checking the LED color below it. Red is 0 – 25%, orange is 26 – 60%, yellow is 61 – 90% and green is 91 – 100% battery life. The mice can be used while charging.

Glorious model D 2 and O 2 Pro – Performance

On Windows 11 Home, with a 3440 x 1440 main display and a desktop that extends to the right to a 2560 x 1080 secondary display, I found the pointer movements to be smooth and accurate at 1600 DPI. The optical switches provide quick button response and a satisfying click.

As is now standard with high-end mice, the four 100% polytetrafluoroethylene (PTFE) mouse skates allow the mice to glide effortlessly over most surfaces and are ideal for combining with a good mouse pad. The D 2 series even includes additional mouse skates that can optionally be placed between the upper and lower feet for even more speed. For me, the extra speed was a bit much, but I love that the option is there for D 2 series mouse owners.

Combined with the feather-light weight of each mouse: 57 g for Model O 2 Pro 1K, 59 g for Model O 2 Pro 4K/8K, 60 g for Model D 2 Pro 1K and 62 g for Model D 2 Pro 4K /48K, Being able to react quickly in the game really comes down to the limits of your own reflexes. In short, all the performance you need is yours for the taking.

Thanks in part to the fact that they weigh about half the weight, each of these mice easily surpasses the movement speed of my previous favorite in this area, the Corsair Scimitar Elite Wireless. While none of these mice have anywhere near the same number of programmable buttons as Corsair’s top-rated wireless mouse, there is something positive to be said about the Glorious Pro’s sleek chassis in terms of relative comfort.

For my own PC desktop setup, I connected a lot of devices, including a lot of wireless devices of all types. As such, I found myself experiencing stuttering and freezing when the 1K’s 2.4GHz wireless USB receiver was plugged directly into the front of my PC’s USB-A port. Fortunately, Glorious anticipated this problem.

Using the included Wireless Extender Dongle, which has a USB-C port on one end and a USB-A port on the other, I was able to connect the Type-A to Type-C Paracord charging cable to the front of connect my PC to the USB-C port of the Wireless Extender Dongle. I then connected the 2.4GHz wireless USB receiver to the USB-A port of the Wireless Extender Dongle. With the cable’s length of 6 feet, I had no trouble placing the receiver close enough to the mouse to eliminate any further chance of stuttering and freezing.

Due to their higher performance requirements, the 4K/8K models completely eliminate the two-piece USB receiver and instead opt for a single 2.4GHz 4K wireless receiver that requires the Type-A to Type-C Paracord charging cable or equivalent to to be able to function. While it would have been nice if we didn’t need the extension, it’s nice that the solution to every possible interference problem is already in the box.

These four mice are beautifully designed, but they’re not perfect. Although the mice work on virtually any computing device, only Windows users will benefit from the Glorious CORE configuration software. This can be considered a missed opportunity, as the down-to-earth nature of the mice can be applicable to many different use cases. However, the fact remains that Windows is the operating system that most PC gamers use, so focusing on it isn’t the worst decision in the world.

Another potential disadvantage is that of left-handers. Although the O 2 Pro is shaped for ambidextrous use, lefties will have to awkwardly use their pinky for the two side buttons instead of the thumb that righties are allowed to use.
