The SteelSeries Aerox 9 Wireless is a lightweight MMO/MOBA gaming mouse. Its body has diamond-shaped cutouts to reduce its overall weight, a dedicated CPI button behind the scroll wheel, and a 12-button side panel on the left. It has the same sensor and identical, right-handed shape as the SteelSeries Aerox 5 Wireless, a multi-genre model with fewer side buttons but very similar performance. This mouse connects wirelessly with a USB receiver or Bluetooth and recharges with an included cable.

Unfortunately, while its scroll wheel has L/R tilt buttons, it lacks a free-scrolling mode.

Performance-wise, you can set your CPI precisely within a broad range, and the minimum lift-off distance is very low. Unfortunately, while the click latency is very good, it isn't as low as some similarly-priced options.

It has a full 12-button side panel, and you can reprogram all buttons using the customization software, which is compatible with Windows and macOS.

The SteelSeries Aerox 9 Wireless is a good mouse for travel use, but it's bulky and isn't designed for storing in laptop bags or cases.

The SteelSeries Aerox 9 Wireless has a matte black plastic outer shell with diamond-shaped cutouts on the top, bottom, and on parts of the left- and right-click buttons. There's a SteelSeries logo on the left click button and three RGB zones. One RGB zone is located inside the mouse, visible through the cutouts. The other two RGB lighting zones are in a strip that wraps around the back of the mouse at the bottom. This mouse looks very similar to other mice in the SteelSeries Aerox lineup and is visually identical to the SteelSeries Aerox 5 Wireless.
The SteelSeries Aerox 9 Wireless feels very well-built. The perforated plastic body feels very sturdy and exhibits very little flex. There's a small amount of side to side wobble in the left- and right-click buttons, but this isn't noticeable during normal use. Like with the SteeelSeries Aerox 5 Wireless, there's a very faint rattling noise if you shake the mouse very aggressively, but this isn't noticeable when using the mouse normally. Unlike the Aerox 5 Wireless, this mouse doesn't creak when the shell is squeezed aggressively. This mouse is also IP54-rated, which provides moderate protection against dust and spills.
The SteelSeries Aerox 9 Wireless has a right-handed shape identical to the SteelSeries Aerox 5 Wireless and the SteelSeries Rival 5. If you have small or smaller medium-sized hands, you may not find the mouse comfortable as it's on the larger side. Overall, the button placement is good, and they're well-spaced to avoid accidental button presses.
If you have small hands, you can't reach the forward-most side buttons without adjusting your grip position using a palm grip.
If you have small or medium-sized hands, you may not comfortably reach the side button that's furthest forward without changing the position of your hand using a claw grip.
This mouse isn't well-suited for a fingertip grip. Only extra-large hands will likely use this mouse comfortably without adjusting their grip to hit certain buttons using a fingertip grip.
SteelSeries advertises that the SteelSeries Aerox 9 Wireless has a battery life of up to 80 hours while connected with its USB receiver or up to 180 hours connected via Bluetooth. The RGB lighting will flash red when the battery life is 5% or less. Also, when you wake the mouse or turn it on, it will flash either red, yellow, or green to indicate the remaining battery life.
The SteelSeries Aerox 9 Wireless has a mesh charging cable. This cable resembles a hybrid between a braided and paracord-like cable. The cable feels high-quality, but it's much closer in flexibility to a braided cable rather than a paracord-like.
The SteelSeries Aerox 9 Wireless has superb, rounded feet that glide very smoothly on mousepads and desks. There's a faint scratching sound when moving on both surfaces, but there isn't any noticeable drag.

You can program all buttons on this mouse, including the up/down and left/right scroll inputs. SteelSeries advertises that the left- and right-click buttons use Golden Micro switches with a rating of 80 million clicks.

The SteelSeries GG software is modern-looking and easy to use. It lets you remap buttons, program macros, configure battery-saving modes, set custom RGB lighting schemes, and precisely adjust your CPI. This mouse also has onboard memory, but it doesn't let you save macros or custom RGB lighting settings.
