Steelseries Aerox 9 Wireless MMO Mouse Review

SteelSeries is a brand synonymous with innovation over the years. Even in their early days, the goal of creating innovative and functional peripherals for gamers has been a core part of the company. I still long for the discontinued Merc Stealth keyboard because it was such a functional and unique board to use (seriously SteelSeries, it needs a comeback tour).

Their latest innovation venture takes the form of the Aerox 9 Wireless MMO Mouse. Featuring 18 programmable buttons, a proven software suite, and no added weight, this mouse is fighting for the championship. Compared to other mice in its class, the Aerox 9 aims to be slimmer and meaner than the competition, giving MMO gamers a new peripheral to consider for their setup. How well does the Aerox 9 stand up to the hype? Grab that coffee, relax, and find out in our review of the Aerox 9 Wireless MMO Mouse courtesy of the good folks at SteelSeries.

Smart design

The Aerox 9 Wireless is a stylish mouse. Using the same design philosophy as the rest of the Aerox range, this MMO mouse features the iconic grid design the series is known for. Its long, narrow body and palm grip make it exceptionally comfortable to hold in your hand. With its slim profile, the side buttons of the Aerox 9 also adopt an elongated horizontal design, which keeps everything neatly stored along the side of the mouse.

Due to its slim profile, you won’t find any type of finger rest that might look a bit odd with modern MMO mice, but it didn’t detract from the overall comfort of the mouse. The left and right mouse buttons are quick and responsive and produce a very satisfying click when activated. The scroll wheels have a rubberized finish and are easy to use with a firm, tactile response when in use. A single DPI button sits just behind the scroll wheel and lets you easily switch between settings.

The Aerox has 3 zones of 16.8 million RGB colors to work with, all customized from the GG Engine software (more on that in a moment). Most impressive is the actual weight of the Aerox 9. At just 89g, it’s actually the lightest MMO mouse I’ve ever worked with. The overall quality and usability of the Aerox 9 Wireless is a great match for every SteelSeries product I’ve used. It’s solid, smartly designed, and manages to strike a great balance between function and functionality.

Function and Features

The Aerox 9 Wireless comes with quite an impressive list of features. 18 programmable buttons are available, each fully customizable to your needs. With profile saving, it’s easy to quickly swap settings between games, allowing the mouse to easily adapt to your needs. The DPI button can also be programmed to switch between pre-saved profiles (or configurations), meaning you can essentially hot-swap your profile on the fly.

As much as I appreciate the look and design of the side buttons, I noticed that I struggled a bit with their placement. As mentioned, the Aerox 9 has a long, slim body that looks great and fits well in my hand. However, the cost of this design is that the side buttons themselves are also elongated, making the one-to-ten button reach an uncomfortable stretch, even for my long thumbs. This is by far the furthest I’ve had to reach on an MMO mouse. It’s something I’ve learned to adapt to and now I don’t feel too awkward, but it’s not as comfortable as some of the other MMO mice I’ve tested and used.

The Aerox 9 also sports IP54 protection. That means things like dust, dirt, and grease from last night’s pizza won’t ruin your perfect K/D ratio in Apex. It also makes the mouse easy to wipe clean if you encounter debris on your one to six buttons. I’ve noticed that despite the last three weeks of use, the Aerox 9 still looks shiny and new, with no major smudges or dust buildup.

I was also impressed with the battery life. The Aerox 9 is capable of a 2.4 GHz wireless connection via a USB or Bluetooth 5.0 receiver. When using a traditional 2.4 GHz wireless connection, you can expect around 80 hours of active use before recharging. Bluetooth more than doubles that score to around 180 hours.

Despite my best efforts, I haven’t completely drained the battery yet. After three weeks of use as the main driver at home on my gaming PC (connected via 2.4 GHz) and at work (connected via Bluetooth 5.0), I still have 15% battery life. This ability to switch on the fly between wireless and Bluetooth really eliminates the need for multiple mice, which is something I’ve always struggled with.

Using it as my primary mouse all day and night, I was impressed with how smoothly the 9 glides over different surfaces. Aerox underside is 100% equipped PTFE Glide Skates that move smoothly. This material excels at creating a low-friction point of contact that not only enhances movement, but also the smoothness of that movement. It sounds great on paper and I’m really impressed with how well it works in real life.

The Aerox 9 also features Steelseries’ new TrueMove air sensor which is intended to create the most accurate reflection of hand movement possible. Every movement is recorded and translated to the screen creating a very natural fluid motion. In practice, it works exceptionally well. Compared to another top brand MMO mouse I have here for testing, I noticed a difference in translated motion response. Essentially, the TrueMove air sensor was more responsive to my hand movement, meaning I had to move my hand less to get the same result as with the other mouse.

It presents a bit of a learning curve for gamers, but once I figured out the sensitivity it felt surprisingly natural to use. For those worried about the sensor being overzealous, all of these settings and a host of others can be customized and tweaked to your desired feel.

GG… GG Motor

I’m pretty critical of software for gaming peripherals. It seems there are really only two philosophies when it comes to their design. It is either a carbon copy of a generic software package or the most robust and feature-rich software suite you can install. Fortunately, GG Engine leans towards the latter offering exceptional control over what you can customize and save on the Aerox 9 Wireless.

The GG engine has no problem picking up a new SteelSeries device that it supports. In the case of the Aerox 9 Wireless, I simply plugged in the wifi adapter and turned it on. Within seconds I was navigating through the Aerox settings with no additional configuration. It was that easy and made getting everything up and running a breeze.

Each button is fully editable, allowing for some serious customization. With what SteelSeries calls Configs (profiles), you can really customize to your liking. Customization, however, goes beyond adjusting the buttons. Everything from CPI (count per inch) adjustments to poll ratings can be changed. It really is an impressive array of virtual buttons and dials that make the mouse feel personalized.

Despite the number of options available, GG Engine doesn’t feel overwhelming to use because you can adjust as much or as little as you want. The only interesting remark I had when testing the DPI switching was that there was a small timing issue between the DPI switching which is instantaneous and the RGB color change. In all my tests, the color change was delayed by about a second. It has absolutely no impact on gameplay, but it can get a bit confusing if you have a lot of saved DPI profiles and are quickly swapping them out. Overall, the GG Engine is one of the best software suites I’ve used to customize a mouse.

Final Thoughts

The Aerox 9 Wireless lives up to the Steelseries standard of innovative and creative peripheral design. It’s packed with features and functions that make it a strong contender for those looking for MMO mice. From excellent software support to smart design, the Aerox 9 has a lot to offer. Some minor design decisions like the elongated side buttons and the lack of a finger rest might be a slight drawback for some. However, compared to everything the Aerox 9 has to offer, it’s hard to find many other mice that can go against it. Not to mention that it is a good price ($149.99 MSRP), compared to other MMO mice with the same features and functions. Hands down, the Aerox 9 Wireless MMO Mouse is one of the best mice in its class.
