SteelSeries Aerox 9 Wireless - Holey RGB Gaming Mouse - Ultra-lightweight Water Resistant Design - 18 Buttons Bluetooth

I've only had my hands on this mouse for a few hours at this point, so I can't truly speak to how good or bad the battery life is. However, my initial impression is that this mouse more than serves its purpose. Regarding the SteelSeries GG/Engine functionality, I can safely say that the range of customization options, both for RGB and for the actual hardware, are expansive enough to leave even the most finicky of performance tweakers' content. For the accessories, I have a bit of an issue with the USB-C 2.4 GHz dongle. I'm using this mouse on a laptop with a single USB port, and having the dongle in said port effectively blocks me from using the adjacent USB-A port and one of the audio jacks. While using the mouse over Bluetooth is a solution, that does reduce some of the functionality, and felt like it introduced a bit of latency. The extender and braided USB-A to USB-C cable used to connect to the extender AND charge the mouse are pretty high quality and are honestly an expected inclusion for a mouse like this. For actual gameplay usage, the mouse does its job well. My only complaint is that in exchange for the iconic lightweight design the Aerox line offers, I'm making some sacrifices. I primarily purchased this mouse so that I don't have to steal my Logitech G600 from my desktop while using my laptop to play my favorite MMO. But the bulky G600 has a feature I'm having trouble to adapting to the Aerox 9 lacks: The third click button that when pushed in conjunction with the side keys, inputs them with the Control key modifier (1 becomes Ctrl+1, etc.). The reduced weight, better portability, and wireless functionality is a worthwile trade off, I feel, but this may not be the case for you if you are accustomed to having that ease of access in MMOs. Finally, we come to my main sticking point with the Aerox 9. The ergonomics. They are *mostly* flawless... With one glaring issue. When using the side keys, my thumb rests nicely on the second row where they have a nice nub to indicate where you are on the keys. But to reach the *top* row requires me to stretch and slightly rotate my hand in order to get a sure feel for which key I'm pushing and to reliably do so. This can be mitigated somewhat by resting your hand slightly higher up on the mouse, but this also takes away from the good shape of the mouse somewhat. If SteelSeries ever does a refresh on the design, I encourage them to look into bringing the side keys back towards the bottom of the mouse maybe even just two or three millimeters. In the end, I feel like this mouse can give you what you need if you are looking for a wireless MMO mouse, being one of the only ones available from a major, reputable brand that I've found. The mouse's software gives you full range to customize it to your needs, and the lightweight design makes most other MMO mice feel like bricks by comparison. The ergonomics issue can be overcome with adapting how you hold it somewhat, and it trades some functionality for the lightweight design. The dongle's width should be a non-issue for most users, and the accessories included are of a high quality. I do feel like I could safely recommend this mouse to a friend who needs a MMO mouse that has to be wireless, and perhaps even if they're just more accustomed to lightweight, low-profile mice than the monster-sized mice that most MMO mice are. *I may update this review down the line once I've gotten more experience with it.

I want to preface that I am an outlier. I have an amazing blend of long fingers, flexible joints, and short palms. For the pianists out there, I have a 10in span on my right (mouse) hand. Apropos of the above, you will see that many others have commented that the ergonomics of this mouse are poor, to say the least. This is a tragic understatement of the embarrassing design of this mouse. I'm most comfortable between a fingertip or claw grip, I often find I swap between the two. However, I am plenty comfortable with a traditional palm grip, especially for longer and larger mice. I **cannot** find a comfortable grip with this mouse. Holding it in a claw or fingertip grip means I'm either holding it short of the mouse buttons, or I must completely curl my thumb in a very dramatic claw to actuate the side buttons. In either pose, the "2" button is nearly impossible to detect, as it abnormally small compared to every button near it. Trying to hit just the "2" button and no other button is a nightmare,and considering that many games have "sour" buttons, wherein hitting the wrong button will cause a delay in the intended action, this is simply unacceptable. Exacerbating all these issues, these buttons are among the squishiest and least tactile of any mouse buttons I've ever used. Redragon slop has better feedback than these, and they cost 1/3rd the price. I tried to hold the mouse on a canted angle, to see if I could work around this with a bit of adjustment. Never you mind that this is already a bad idea (see movement angles) but when I did so I quickly found that the left and right click buttons were simply too short to accommodate a sort of mid-body grip that canted angle required. In my experience, there is no way for me to comfortably actuate all 12 side buttons and keep a comfortable grip on the mouse. If the "1" "2" and "3" buttons were replaced by the "4" "5" and "6" buttons (and another row were added at the back to make up for the loss) maybe I could recommend this mouse. tl;dr, it is an awkward and comically incompetent design. I've never bought anything SteelSeries before and I highly doubt I'll ever buy anything from them again. EDIT: It's been just about 2 weeks since I started using this mouse and it no longer stays paired with the provided 2.4ghz dongle. Pairing with BT works fine, but has some noticable latency. That could just be my BT card, but the lack of connectivity with the dongle is unacceptable after only 14 days of use. Even more damning, I have been busy with work, so I've only spent about 20 or so hours with the mouse. Another issue I've noticed is that the battery level is incredibly unreliable. It will flash red for low battery after about 15 minutes of use, but it seems to still have a "normal" battery life. Time will tell if that's another canary in this coal mine. ymmv, but I'm going to steer everyone away from these mice in the future. Razer mice might die within a year or two but at least they'll make it longer than 2 weeks and can actually report their battery level with some accuracy. The only positive I can give this is that their software is less blighted than Synapse, but you cannot save or switch profiles to the mouse. Read more
