MMO mice aren't for everyone, and the array of buttons on the side can take a lot of getting used to before its really functional on the fly. But the Corsair Scimitar Pro offers a lot to like even for gamers who won't be using all of its side buttons, and the fact that the side panel can be slightly adjusted forward or backward can help first-time MMO mouse users find a configuration that's comfortable for them.

The Scimitar Pro is an update to 2015's Corsair Scimitar, and while not much has changed on the outside of the mouse it now sports an improved internal sensor that bumps the max DPI up to 16,000.

The Corsair Scimitar Pro is currently available on Newegg for $79.99

Design and Comfort

The Scimitar Pro comes in two colors, an all-black version we used for this review and a yellow-accented model. While the black model might fit more seamlessly with every desk setup, the yellow accent highlights the keypad, which is the real selling point of this particular mouse. The yellow also gives the mouse a cool construction equipment vibe, and the previous Scimitar model worked very well in our Doom PC setup from last year. 

There are four different RGB lights that can be independently adjusted on the Scimitar Pro: the scroll wheel, the "headlight" on the front of the mouse, the Corsair logo under your palm, and the backlighting of the side button grid. Corsair's software allows you to control your mouse lighting and have it cycle through a rainbow spectrum, pulse from one color to another, or simply stay illuminated in a color of your choice. The lighting does its job fairly well, but compared to other gaming mice the Scimitar Pro doesn't sport the brightest or the most interesting lights around. 

There is one additional light on the mouse, on the left-hand side right in front of the keypad itself, which you frustratingly can't customize or even turn off. This was an issue with the original Scimitar as well, and has to do with this light being tied into the mouse's DPI and button profiles. You can cycle between the different profiles on the fly, moving from red to yellow to green to blue on this side light, but if you actually want to adjust the color you need to do it via the DPI settings in the software, which is confusing and different from the way all the other lights on the mice work. 

Corsair has done just about everything in their power to make the MMO buttons on the side of the Scimitar useful and easy to find in the heat of virtual battle, short of following SteelSeries down the path of a non-standard layout. Anyone who is comfortable using a 12-button side pad will be right at home with the Scimitar Pro, and those who are new to it will find adjustment easier thanks to the alternating texture of the button columns and the comfortably curved design of the whole pad.

Even better, the Scimitar Pro's entire number grid can be adjusted up to 8mm along the front-back axis of the mouse. To enable the adjustment you use an included Allen key, and you can then ensure the pad is in the most comfortable possible position for you. This adjustability is a fantastic inclusion in an MMO mouse, as a common complaint with other models is that certain buttons, often those in the rear, are just not in a location that's easy or comfortable to reach. 

Still, some MMO mouse fans might not like the relatively flat and flush nature of the Scimitar Pro's pad compared to the rounded, convex buttons you find on mice like the Razer Naga. Either style is something you can get used to with time, and both have associated pros and cons. I found the Scimitar Pro's pad more comfortable to use thanks to its concave nature, since my favorite mice are always those that curve inward under my thumb. 

Features and Performance 

The update that sets the Pro apart from 2015's Scimitar is the new PMW3367 optical sensor, a custom version of the popular high-performance sensor from Pixart developed specifically for Cosair. The mouse is now capable of up to 16,000 DPI, up from 12,000 in the previous model, and the sensitivity can be adjusted in one DPI increments, which is just the kind of ridiculous overkill gamers love in mice. 

In practice with games including OverwatchDoom, and Dota 2, the Scimitar Pro is a solid performer but not as agile or fast as the top non-MMO mice on the market. Its 0.27 lbs weight puts it in the same ballpark as many other popular gaming mice, though Corsair's measurement doesn't include the mouse cable while many other companties do include the cable in their weight listings, so pay close attention to that when comparing your options.

Regardless of the exact weight, the Scimitar Pro just feels a bit more deliberate and less springy in the hand, and wouldn't be my first choice for fast twitch shooters, but it's clear with its array of side-buttons that's not the genre for which the Scimitar Pro was specifically designed.   

One of the very best features of the Scimitar Pro, as should be expected, is the feel and function of its side buttons. The alternating textures of the button columns help you find the right button in a flash, and the mechanical click response you get when hitting a button is significantly more satisfying and tactile than what I've found on other MMO mice. This clicky feedback combined with the adjustability of the entire side button panel means the Scimitar Pro just might have the best MMO button grid on the market. 

Corsair's robust CUE software is among the more powerful such programs on the market, and is much easier to use than it was a few years ago. With CUE you can program button functions, design macros, and set advanced features such as specific DPI settings (so you can set up your own "sniper" button) and MMO timers. The Scimitar Pro can also be "tuned" to your specific mouse pad or desk surface, if you're the kind of person who obsesses over the fine details of mouse accuracy and performance.
