SteelSeries Aerox 9 Wireless - Holey RGB Gaming Mouse - Ultra-lightweight Water Resistant Design - 18 Buttons – Bluetooth/2.4 GHz - 18K DPI TrueMove Air Optical Sensor

I saw this for the first time the other day and waited for a sale... and initial impressions are fantastic. It's way lighter than I'm used to, so tracking will take a bit of getting used to. Bluetooth option is a major plus for when I travel. The button grid is a bit larger than the Naga, but useable... comparable to the Corsair but the buttons are easier to find with my thumb. The only real downside so far is that the plastic on the right side is slippery (not rubberized). It has been difficult to pick up, it likes to slip out of my hand when doing liftoff maneuvers. I ordered some grip tape to fix this, so I expect that will be a non-issue soon. As long as it doesn't suffer from tracking issues 6 months in like every Razer I've owned, I think this will be my #1 MMO mouse for the foreseeable future.For a bit of background.... I've been using MMO mice exclusively for my MMOs for the last decade or so. I've tried all the major brand MMO mice. Started with the Naga when that first came out. Tried the G600 and the Corsair one when those came out. Bought a lot of Nagas over the years(3 wired and 4 wireless), they all had tracking/skipping issues within about 6 months (as do all Razer mice I've tried). Eventually I would start swapping them I had so many. When one would act up I would grab a spare. That one would work again for a little bit and I would have to swap again. I had 5 different PCs/laptops I used over the years, so I knew it was a mouse issue and not my computer. Once they had started making wireless versions, I was stuck. When I tried the G600 for a bit, I had to go back to the Naga because the G600 is massive and hard to maneuver. The Corsair turned out to be an excellent option, but their software is awful and no wireless was a problem when I wanted to travel, so it stays with my desktop now. I'm honestly surprised we haven't had another wireless option sooner... I know this probably came out a while ago, but I also don't play MMOs as much as I used to... mostly just play FF14 casually these days.

2nd unit updateThis 2nd unit of mine Aerox 9 Mouse, after 7 months of use, failed on scroll up and down again. I bought Aerox 9 the first one failed the scroll up and down in 10 months, there was zero dirtiness inside no hair no dust whatsoever, they gave me a new mouse for free that one lasted about 10 months, which then ran out of service period and had to buy the second one. Now the second unit also kept clean failed on the scroll up and down again. This is the third time I had this issue. I hate this mouse and would have been much happier without it.24 month updateThe scroll up and down failed again. The replacement mouse I got from warranty did not hold up long enough. Funny it's middle, left and right click works, but the scrolling up and down does not. Exact same problem I had in 10 month update. Therefore, I put 1 less star for review from 4 stars to 2 stars. Do something about it Steelseries. You guys do realize it is 2025? how a simple scroll up down can fail so frequently and repeatedly? Great mouse, not the most ergonomic but not an issue for me, but scroll wheel just made this mouse a big regret for me.10 month updateThe wheel scroll died. It took me 3 weeks to get a new mouse off warranty. Funny thing is that Ive been using a faulty mouse all along. When using 2 applications, say a browser and a game, you can have 2 functionality from the mouse. For example left wheel scroll click for previous page while using a browser and f1 key for game. But the first mouse did not work properly in this regard. The one i got for replacement works seamlessly. All in all i dont have such a great impession on the steel series products and the customer service . The people working there are not alert and dont do their best to help tue customers or describe the procedure. I had to ask same question over and over because they copy paste not very detailed answers and even unclear answers to what I ask from their respond. So i go from 4 stars to 3 stars. Nice product, bad quality control, and laughable customer service.one tip!If you want to use this mouse for longer period of time, I suggest you clean the inside of mouse with air blower. My mouse upon destruction for warranty activation showed some dusts and short hairs inside, which could have caused the problem. I dont think the air blower will completely clean up the inside, but I believe it is worth maintained that way because this mouse has holes everywhere making it susceptible to dust and debris gathering inside.Original reviewAfter about a month of use, I can confirm this mouse is legit except for the battery life that lasts only about 40 hours of heavy MMO use in 2.4Hz connection without RGB. If RGB is turned on, I think this mouse will last only about 12 hours. I’ve had one other MMO mouse before, G600, and I like the Aerox 9 a lot more though G600 had angled buttons to allow users to find the buttons easier in the beginning. Side button positions and layout is just as good on both mouse. It’s about the same difficulty of pushing side buttons. In the most comfortable grip, my thumb finds 4-9 naturally, but 1-3 and 10-12 is not a problem to push. Since Aerox 9 is much lighter than the G600 and has no cable connection, it is easier to maneuver in my hand and find those 1-3 and 10-12. The mouse also is not humongous like some people make it out to be. I am 5ft 9 and have a fair sized hand. My hand is definitely not big for my size. When I put the mouse under my hand in natural comfortable grip, I have a small wiggle room between my wrist and the end tail of the mouse. I don't play game in this comfy grip tho. I put my wrist as close to the tip of the mouse tail so thumb is close to side button 1,2,3 as it allows moving the mouse around more accurately. However, like I said, the mouse is so light, it is easy to tilt/move inside my hand so finding numbers 7-12 isn't a problem. The click sensation is very nice and there is no latency issue at all. Zero.The real problem of this mouse is the Steelseries Engine software and the customer service. One time, I asked a few questions to the company and it took them 10+ days to reply. The DPI adjustment is only available in 100 increment. A 50 increment up and down would have made a world of difference for me, but the software can only do 100 plus or minus, so fine tuning is not the best. The mouse also does not go back to normal button configuration setup once you engage a game connected to the Engine software. If you start a game bind to the custom button configuration via Engine, the button configuration will stay in a game setup even after the PC turned off and turned back on. I had to open the Engine software to go back to my normal web browser button setup.One tip. Get a magnetic USB-C connector + cable for charging. It’s much easier to connect the charger that way. The charging port is positioned a little hard to connect, but with magnetic dongle and cable snaps right in.
