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.
Our Verdict

Test Results
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.
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. If you're interested in an MMO-focused wireless mouse that has hot-swappable side panels with different button layouts, check out the Razer Naga V2 Pro.
The SteelSeries Aerox 9 Wireless has impressive click latency. It feels snappy and responsive for gaming, but it isn't as low as some high-end gaming mice.
The SteelSeries Aerox 9 Wireless uses a proprietary TrueMove Air sensor, based on the PixArt PAW3335. The polling rate options are 125Hz, 250Hz, 500Hz, and 1000Hz. You can set up to five CPI settings per user profile and cycle between them using the dedicated CPI button behind the scroll wheel.
The scroll wheel has a grippy rubber surface, and its steps feel smooth but well-defined. It's also fairly quiet.
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.
