Glorious Model D 2 Pro & Model O 2 Pro Wireless 4K/8K Hz Review

Both this, the Glorious Model D 2 Pro, and this, the Model O 2 Pro, are remarkably similar mice, and seeing as Glorious sent them over at the same time, I figure why not take a look at them both in one neat video? These are actually rather interesting mice, namely thanks to these two stickers on the box. The Model D 2 Pro weighs just 64 grams, and yet can do 4,000 hertz polling wirelessly, or 8,000 hertz polling when wired. Razer does have their newest Deathadder V3 Pro that I’ve been waiting for Razer to send me their HyperSpeed Wireless dongle so I can actually use it at 8,000 hertz wirelessly, but that dongle is actually a separate purchase. These Glorious mice come with their 4,000 hertz dongles in the box, so let’s test them and see if they are worth grabbing – especially over that Deathadder. 

I’ll start with the Model D, that is a high-arch design that’s on the larger side, so while my large hands fit it just fine, smaller hands might struggle. It’s pretty high in the centre too, so you’ll want to palm or claw grip it, although for me it’s actually pretty comfortable. The side buttons are nice and big, placed well so you won’t hit them accidentally, but they are in an easy to access place too. They are well supported, nicely tactile, and generally a nice feel. You’ve got plenty of space on both sides for your thumb and ring/pinky fingers to grip the shell, not that you need to grip it particularly hard thanks to the distinct lack of weight in this thing. It’s beautifully light, which does make flicking it around at a low DPI pretty easy – but we’ll get onto that in a sec. Build quality feels good – they’ve opted for a solid shell, rather than the honeycomb design from the older Model D and D 2, which I think I prefer personally. It still feels solid though, even with a decent bit of force. 

The Model O, by contrast, is much flatter. It’s also symmetrical, although the considerably smaller side buttons are only on the left. This shape is better suited to claw or fingertip grips, although people like me with larger hands can still palm grip it if you prefer. It’s much more suitable for people of all hand sizes, although for me personally it isn’t quite as comfortable as the D. I like gripping the D much better. Sorry, I couldn’t help myself. Those side buttons are still placed well, and relatively easy to hit, although not quite as good as the Model D’s ones, and you definitely have less space to grip the mouse with on either side, although the even lighter 61 gram weight means you don’t exactly have to grip it tightly. Build quality here is good too, again no creaks or rattles. 

As for accessories, both mice come with a USB dongle which takes the supported USB C cable in, which I actually quite like as a desktop user – since you will need the cable to charge the mouse, having the cable plugged into the dongle (and on your desk, near the mouse for the best connection) means it’s then available to swap between, rather than the standard USB A dongle which means you need both the dongle plugged in, and a spare USB cable to occasionally charge it. The downside is that for laptop users, having this long cable with a dongle on the end is somewhat inconvenient compared to a tiny dongle that can just stay attached to your machine. I’ll leave it up to you whether this solution works for you! As for the cable, this is a gloriously soft cable that is really light, doesn’t snag, and just feels fantastic. I really like this cable. One thing the Model D 2 Pro gets that the O doesn’t are these extra PTFE skates. The default skates are on the smaller side, so if you want more surface area, these come in the box – although sadly that option isn’t there for the O. 

Both mice feel really good in motion, even with the default skates on the D, it glides well. The light weight makes it really easy to flick around without fatigue, and makes it quite easy to be accurate with too. Both mice use Glorious’ BAMF 2.0 26K optical sensor, which is, at least by name anyway, the same sensor you’ll find in a lot of their non-8000hz mice. Knowing it’s likely a PixArt sensor, it looks like the PAW3395 matches the specs, so if I had to guess, that’d be it. Unsurprisingly, that sensor tracks rather well, and at least to the eye it doesn’t feel like this suffers from the start delay that some of the older Glorious mice have been known to suffer from in the past. I am working on a new motion latency test mode for my new OSLTT CS tool, but that’s not quite ready yet. 

Speaking of the latency tool, well first if you want one of these bad boys, you can pick one up at OSRTT.com which is linked in the description, and second, using the new peripheral testing kit, I can finally give you some hopefully useful measurements of click latency. Both of these mice use optical switches, and of course with that high polling rate we should have very little click latency. For context, a lot of 1,000 hertz mice will generally return results around 4 milliseconds here, as this testing methodology includes the pre-travel time, which even when smacking the buttons tends to be in the one to two millisecond range. So, how do these fare? Well, when connected wirelessly, with the polling rate set to 4,000 hertz, it’s around 2.43 milliseconds of latency. That’s pretty decent – the lack of a debounce delay and the high polling rate definitely helps there. What about wired at 8,000 hertz though? Well the thing about these high polling rates is that you start to get diminishing returns. At 4,000 hertz that’s a new packet every 0.25 milliseconds. Even if you assume you always miss one, that averages out to half a millisecond of latency, compared to two milliseconds at 1,000 hertz. 8,000 hertz is 0.125 milliseconds, or 0.25 milliseconds on average. That’s not exactly massive – so when you see that the average latency drops to 2.18 milliseconds, well you can see there isn’t a super massive difference. It’s better, for sure, but not hugely. 

By the way, if you want to customise the mouse, both for polling rates, strangely debounce delays – something you shouldn’t need at all for an optical switch – and lift-off distance, you can do so in the Glorious Core software. It’s pretty easy to use, reasonably well laid out, and has all the settings you’d expect, including DPI, profiles, and the ability to split the polling rate between wired and wireless. You can also do firmware updates through here when they become available.

As for actually gaming on them, in short, I’m pretty happy with them. The Model D feels better in my hands, but both track well, are pretty fast on the reactions front, the light weight bodies mean they are really easy to control even for longer play sessions, and just outright feel good to play with. They claim 80 hours of battery life – although the polling rate will affect that if you leave it at 4,000 hertz, but with how nice the paracord cable is, and how you get a better experience when wired anyway, you might find yourself using it primarily as a wired mouse anyway.

In short, I really like these mice. As I’ve said, the D is my preference, but the O is definitely a more widely-suitable choice. Both of these come in at £120 which definitely puts it at a premium price point, although that DeathAdder V3 Pro with the 8KHz dongle is more like £150, so these look positively good value by comparison! Realistically, if you’re in the market for a premium, light, and fast gaming mouse, either of these do like decent options, and get a recommendation from me.
