Battle For The LIGHTEST Gaming Mouse – MM710 vs Glorious Model O-

The Glorious Model O- versus the Cooler Master MM710 are the two mice that I have used daily for the past two weeks. Now that I’ve gathered a bunch of hands-on experience I want to break down everything you need to know about these two models and which small and light mouse might suit you best.

Price & Packaging

Let’s begin with the price, both mice start at $49 USD with a $10 premium for the glossy version of the Model O-. I love the dual color and surface options for the Glorious, my favorite being the matte white as I don’t really like how the glossy surface feels to the touch. The MM710 is supposed to come in all the same colors and surface options, but they’re not yet available except for the matte black. With regard to design, the Model O- is a beautiful honeycomb mouse with awesome RGB elements on the sides and the scroll wheel, while the MM710 is basically bare bones, with no illuminations, and perforations in the shape of the Cooler Master logo.

The packaging of the Glorious Model O- is incredibly impressive for the price point and it really stands out. By comparison Cooler Master’s presentation doesn’t even deserve a mention. The MM710 is available on Amazon with cheap shipping, while the Model O- is offered directly through Glorious. I will say the Glorious mouse probably has better resale value, because the original Model O is selling right now on Amazon is about $30 over the original retail price, and you will never see that with the Cooler Master.

Build Quality & Ergonomics

The build quality of the Glorious feels better with smaller perforations on the frame and no rattling in the internals. However, the internal components on the MM710 are coated to protect against dust and moisture. As I mentioned in my original review of the MM710, they have strengthened the body so that the sides don’t flex as much as the pre-production models, and the buttons don’t have too much sway left and right, but the rattle is still present.

Now weight and size are probably why these two mice are getting so much attention. The MM710 on my scale is just under 55 grams, while the Model O- is two grams heavier. And honestly in real world use this two gram difference is indistinguishable. However, when I put my original Model O on the scale that thing feels like an elephant now, quite heavy, quite bulky, but still awesome in my hand. However, in comparison to both the MM710 in the Model O- the 15 gram difference is pretty noticeable. Overall though, it will definitely be the shape that will nudge you towards one or the other. The Model O- is skinnier, it’s longer, and it’s shorter, so it’s truly for small hands. While the MM710 is wider and taller, which with my hand size and hybrid grip is actually very comfortable because the back curve is not as smooth as on the Model O-. With the Glorious mouse I lose that bit of palm support at the back, while the Cooler Master accommodates me well.

They are both ambidextrous shapes with thumb buttons only on the left side, and even though the Model O- did not immediately feel as comfortable as the MM710 I was pretty comfortable with it after using it for two days exclusively. I did have to readjust my grip though, as my pinky would fall off the right side and I was dragging it on the mouse mat. The taller body on the MM710 was enough to support my ring and pinky fingers. Of course, this will not be an issue for people with smaller hands, which is why the Model O- exists. It’s just interesting how the MM710 is slightly shorter in length but because of the back curve it accommodates my larger hand much better. I also would like to give an honorable mention to the XTRIFY M4 RGB. This mouse just arrived, it is brand new, and size-wise it is pretty small. It’s slightly bigger than the MM710, but also heavier at 71 grams. If you don’t like a super lightweight mouse this is a really good option and I’ll have a review on that soon so stay tuned.

Cords & Buttons

The cords on both mice are very good. It is a shoelace-like paracord on the Model O-, while the MM710 has a more condensed ultraweave that is also shorter and comes with a purple USB ports. I do prefer the cord on the MM710 as it doesn’t kink as easily as the Model O-, plus it’s less bulky. The feet on both are white PTFE, but they are better quality the Model O-, they just feel smoother compared to the MM710. The Cooler Master does however comes with additional replacement set of feet, which is nice.

All right, so let’s talk buttons. Both mice have basically identical layouts. I do prefer the scroll wheel on the MM710 since it has much better control than the mushy feeling the Model O-, while the primary click buttons on the Glorious are super crispy and have shorter travel than the Cooler Master. They both have Omron switches rated at 20 million clicks, and both mice have a two years warranty.

Software & Performance

I do love the DPI color indicator at the bottom of the Model O-, so you always know which DPI you’re using. You can even customize that in the software with up to six DPI levels. While the lack of any lighting on the MM710 means you just have to feel the DPI based on the movement you’re seeing on-screen. And what makes things worse is that there are seven DPI levels in the software that you cannot turn off, so if you’re like me and only use two settings you can go one by one until you set the seventh DPI setting. At that point I set setting to the 16,000 DPI maximum and that lets me know that I’m resetting the cycle. However, it would be nice to be able to turn off the rest of the DPI levels and just keep two.

Now performance wise the MM710 has a higher-end Pixart 3389 sensor with 16,000 DPI, while the Model O- is rocking the Pixart 3360 with 12,000 DPI. It is really hard to distinguish between either as they’re both fantastic and a great extension of your hand for accurate aim. The lift-off distance (LOD) for both is very low around one millimeter and both are incredibly fun to use. If the body shape fits your hand size and grip style, which means fingertip style for the Model O- and hybrid palm for the MM710. The last few interesting bits is both have internal memory built-in, so once you configure them in the software you can move the mouse to another computer without needing to reinstall the software. By the way, both apps are functionally identical, like remapping your buttons, recording macros, debounce time adjustments, and two lift-off distance settings. You can further add surface tuning with the MM710 that might optimize the lift-off distance for that particular mouse mat, but that’s about it.

I want to conclude by saying that at $50 USD both mice are fantastic and they are catered to different hand sizes and grip styles. For me personally, the MM710 is better and it’s all about performance without bling. On the other hand, the Model O- is an awesome release to accommodate smaller hands with fingertip grip without compromising on quality or the visual side of things. I’m really happy that we have such fresh competition in the mouse segment, and I was not expecting Cooler Master to deliver on their promises with the MM710, but the scroll wheel and cord are better on the Cooler Master mouse, while the Glorious is all about RGB, small size, and really just awesome quality.
