Review : Glorious D 2 PRO & O 2 PRO Gaming Mice

Style meets utility with Glorious’ latest gaming mice, introducing the world to the latest PRO gaming mice. Of course, they didn’t simply just send us one of each of these models, they also included high-speed variants of each model, making me review not just two, but four mice total! While I am a fan of quality over quantity, it doesn’t hurt to have options when it comes to comfort, performance, and style. So, is the Glorious D 2 PRO 1K, O 2 PRO 1K, and 4K/8K variants of these Pro mice worth it? Let’s dive in and maybe you’ll find your next professional gaming mouse.

Design & Aesthetics

A while ago, Glorious was kind enough to give us their Model I 2 gaming mice and I absolutely adored it. I never really liked lightweight mice but that mouse turned me into a believer. While I really liked that mouse, there is just one little Problem with it: the battery life. To say the least, it wasn’t that great so I kept it mostly wired the entire time with the braided, super light cable. 

I know why it died constantly and that is because of the integrated RBG lighting, which a lot of people don’t like. Luckily, Glorious has release their own lineup of professional mice that adorn this modern and sophisticated style while also offering ample utility without the flashing lights and rainbow colors, giving me up to 80 hours of battery life on a single full charge. Yes, quite impressive for what is featured inside this lightweight chassis.

You’ll also notice that there are no holes along the body that you have seen in other lightweight mice. I personally prefer this style over the other mice because it is much easier to clean and I don’t have to worry about various compounds making their way into the body. I have two cats and a toddler, meaning there are no rules to the substances that I could unfortunately find in this body. The lack of holes is also great for those who suffer from tropophobia. 

Other aspects of the design that I notice right away is the raised back end of the mouse which positions your fingers in a claw-like position as opposed to a rested position. This style allows you to make quick and precise movements in the heat of battle, making these mice great options for those who play competitive and want both style and functionality.


Perhaps the most obvious design factor is the shape of each mouse. The D 2 family happens to have this curve to it that contours to your hand while the O 2 series has a straight design that could accommodate ambidextrous players. Out of the two, I preferred the O 2 PRO style as it felt more natural to me. If you are someone who doesn’t mind the high-rear curvature, then you’ll feel right at home with the D 2 PRO’s design. 

Performance & Speed

No matter which mouse you choose, both feature a sleek and stylish look sans LEDs besides the charging light at the top and a familiar light at the bottom which tells us which sensitivity setting is currently active by displaying one of several colors. Sensitivity settings along with button programming can be customized with the free-to-download Glorious CORE software, which still remains to be the most user-friendly application I have ever used. 

You also get six Programmable buttons, allowing you to fine tune your in-game experience quickly and efficiently. Left and right 100M switches are pretty snappy and can withstand a ton of clicks without bottoming out or missing clicks. Additionally, you get middle, and two thumb-accessible buttons are all that are present on these devices. It is quite minimal but it makes a lot of sense as to why. For Professional gamers out there, there is less of a chance that you’ll hit something you didn’t want to. As they say, more buttons, more problems.

All of these mice operate on the 2.4 GHz wireless band and do not have Bluetooth connectivity. Some folks might consider this to be a negative, but it has been a known fact that the 2.4 GHz wireless band is more reliable and offers enhanced stability while playing these fast-paced games with wired always coming out on top when measuring speed and latency.

The wireless receiver that is included with the package connects to your system via the (also) included braided cable. This is the same style of cable that came with the Model I 2, so no major change there when it comes to shape and form factor. Except that the 4K/8K variants have a much larger receiver to accommodate the extended polling rate profiles. 

Typical mice have a polling rate of 1000 Hz, including the base D 2 and O 2 PROs, which means that the device is constantly telling the computer its exact position one thousand times a second. The 4K/8K variants expand upon that polling rate, transmitting the respective speeds to your system. While this offers greater accuracy and when paired with a high dpi rating can give you some really solid results, it does eat away at that battery life, going from 80 to 35 hours. 


The only issue I can say that I had with these mice is when the battery starts dying my PC makes the USB plug/unplug sound rapidly. This has confused me many times and has driven me insane, but I came to my senses quickly and realized that the mouse just needed to be recharged. 

Much like the Model I 2, the D 2 PRO and O 2 PRO family are both solid mice that solely depend on how you like your mouse. Claw-grip style isn’t for everyone, but if you are a competitive gamer then I can see a lot of potential here. When it comes to the pricing of each model, the 1K variants come in at $99.99 USD with the 4K/8K models coming in at $129.99. Personally, I couldn’t really tell the difference between performance in either mouse but I am sure that the pros who are training four hours at a time could. 

If you are one of these types of gamers that train, then yes, I can absolutely suggest paying the extra $30 for the higher polling rate. Otherwise, I think the average gamer who is looking for something professional with a long-lasting battery to really enjoy the 1K variants of these mice. They look simple from the outside, but after spending my time with these, it is clear that Glorious has made another great mouse.
