SteelSeriesAerox 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.

I have been trying for a decade to get away from Razer. I can't stand them, but I can't go back to not having an "MMO" mouse. The buttons are useful for all manner of games. I was really excited to try the Aerox 9, having been impressed with Steelseries' Apex Pro keyboard. I'm sorry to say this thing is awful.The biggest problem here is that the mouse both expects you to have very light, small hands, and very large, freakishly long thumbs.The main attraction of an MMO mouse is the side buttons. I have fairly large hands, at about 8 1/2 inches from the base of my palm to the tip of my middle finger, and about a 9 inch wingspan. Unless you're an NBA player, good luck reaching those keys. The side buttons are so far toward the front of the mouse, and add some ridiculous staggered angle, I cannot comfortably reach the 1, 2, 3, or 6 buttons. They're so hard to reach, I have to shift my grip to get at them. Palm and claw don't work. I can't reach the buttons in palm. When I do claw, I invariably add more weight on my index finger. That's when the second major problem shows up.The actuation force on the clicks is absurdly low. This trend in recent years to reduce actuation force / distance is really, really stupid. Speed switches on keyboards, with ~1.2mm actuation, as opposed to the standard 2mm, have shown to have ZERO improvements in actuation speed. It's a gimmick that makes you bad at typing. It seems we're doing this with mice now, too. If you so much as look at the mouse funny, it will click. Unless you have baby hands, you can't rest your finger on the button at all. Having a neurological condition that causes me to shake, I have no choice. My large hands, not large enough to reach the side buttons, are also too large to comfortably use the mouse as a mouse. Lovely.I measured the actuation force of the click at the tip of the button at around 30g. I'm using a scale, so it's not as accurate as a proper force gauge, but it got the job done. My Naga Pro actuated at 45g at the tip. The thing is, with the Naga, I don't have to rest my finger on the end of the button. Not only is it 50% more required force, but I can rest closer to the axis, which means my 70-80g force of a resting finger is less likely to actuate the click. The actuation force is fine when I palm grip, but again, I cannot do this AND use the side buttons, because this thing was designed by Salad Fingers.For perspective, Cherry Brown keyboard switches are 55g. Blue are 60g. Red, being a pretty light switch, is 45g. Keyboard switches are also usually not required to bear the weight of a finger unless you're actively pressing a key. The mouse has to. 30g is too low.Lastly, they replaced their old Engine software with this bloated GG thing. I didn't use it long enough to form an opinion on it, but lighter companion applications are almost universally better.Buy a Naga Pro if you're willing to spend this much. Buy a Logitech G600 if you want to spend 1/4 the money. Hell, I'd recommend a Corsair Scimitar over this thing, and the side buttons on that thing suck, too.Steelseries, you can fix this mouse by moving the buttons closer to the back, making them shorter in length for denser placement (see Naga), and stiffen up the click a bit. If you do that, you have a winner. Unfortunately, you designed the worst of both worlds.
