The SteelSeries Aerox 5 (model 62401) is a wired gaming mouse that packs nine programmable buttons into a 66g shell. This article works through the published specs and the Amazon.co.jp listing data to explain who it fits and what you have to accept in return.
Overview
The Aerox 5 chases two things that normally trade off against each other: low weight and button count. A honeycomb shell keeps it at 66g while still carrying five side buttons and up to nine programmable inputs in total.
The sensor is the TrueMove Air optical unit rated at up to 18,000 CPI, 400 IPS and 40G, with a 1,000Hz / 1ms polling rate.
Think of it as a mid-to-high tier product sitting between two extremes. It is not as specialised as a five-button FPS featherweight, and not as heavy as a twelve-button MMO mouse.
On Amazon.co.jp it holds 4.3 out of 5 stars across 847 reviews (roughly an 86% favourable score, captured May 2026), which is a stable result at that sample size.
Perforated shells usually mean poor tolerance for sweat and dust. The Aerox 5 answers that with an IP54 dust and water resistance rating.
That does not mean it survives a spilled drink, but the design does assume a sweaty, dusty desk.
How to Read the Key Specs
| Spec | Value | What it actually means |
|---|---|---|
| Weight | 66g | Normal for a perforated lightweight; heavier than 50g-class models |
| Buttons | 9 | Five-side-button class; short of dedicated 12-button MMO mice |
| Sensor | TrueMove Air (up to 18,000 CPI) | Most players run 800-1,600 CPI; the ceiling is just a number |
| Max IPS / accel | 400 IPS / 40G | Enough headroom for fast low-sensitivity swipes |
| Polling rate | 1,000Hz / 1ms | Standard for wired; not a 4,000Hz+ model |
| Feet | PTFE | Conventional glide; replacements sold separately |
| Click durability | 80 million | Typical gaming-grade rating |
| Ingress rating | IP54 | Unusual insurance for a honeycomb shell |
| RGB | 3 zones, 16.8M colours | Configured through SteelSeries GG |
The most misread figure here is maximum CPI. 18,000 CPI tells you the ceiling, not the setting you will use.
Most players sit somewhere around 800-1,600 CPI, and how cleanly the sensor tracks in that band matters far more than the headline number. The same applies to 400 IPS and 40G: those are margins that stop the cursor breaking down during large low-sensitivity arm movements.
The polling rate deserves more attention. 1,000Hz / 1ms is fine for a wired mouse, but competing models now offer 4,000Hz or 8,000Hz.
If you are chasing the last millisecond on a high-refresh monitor, that gap marks the Aerox 5's design generation.
Compatibility Guide
Windows and macOS are supported. Button remapping, CPI stage configuration and RGB customisation all require the SteelSeries GG software.
Without GG the mouse still works as an ordinary pointing device, but the nine buttons never earn their keep.
Connection is wired USB only, via the SuperMesh cable. There is no dongle and no battery, so any free USB 2.0-or-later port works.
On laptops with only USB-C available you will need an adapter. It runs through hubs too, but unpowered hubs can behave unpredictably once RGB is drawing current, so plug directly into the machine when you can.
Console use is not something SteelSeries officially covers. Mouse support on PlayStation and Xbox is title-dependent, so "it is USB, therefore it works" does not hold.
If console gaming is your main use case, look elsewhere.
If you move between machines, check whether GG lets you store profiles onboard. Saving CPI and button layouts to the mouse itself means your setup travels with the device.
Confirm this on the manufacturer's product page before buying if it matters to you.
In Use, and What Gets Traded Away
66g sits at the entry point of the "ultra-light" category. Coming from a 100g multi-button mouse the difference is obvious; measured against 50g-class competition mice it is not remarkable.
The Aerox 5's real value is the balance: 66g while carrying nine buttons.
The honeycomb shell divides opinion. It helps if your hands sweat, but some people dislike the feel of the perforation edges, and palm-grip users who rest their whole hand on the shell often get on with it least.
Claw and fingertip grips suit this design better.
The box contains the mouse and its attached cable. No spare feet, no grip tape.
If you want to tune the glide or add grip to a perforated shell, budget for third-party accessories on top.
Comparing Against the Alternatives
At this price you will also find lighter wireless mice, higher-count MMO mice, and newer high-polling models. The decision comes down to which single thing you rank first: wireless freedom, button count, or absolute weight.
If cable-free operation matters most, a wireless mouse will simply satisfy you more; a wired mouse cannot structurally answer "I want nothing dragging on the desk". If you would rather never think about charging and remove one variable from the latency chain, wired remains a sound choice.
If button count comes first, a dedicated MMO mouse with twelve side buttons is strictly more capable. The Aerox 5's nine buttons target people who want a bit more than an FPS mouse offers, not people mapping an entire skill rotation.
The flip side is that 12-button mice are heavier and invite misclicks.
If absolute weight comes first, 50g-class models exist — but they get there by cutting buttons, so you would be giving up the thing the Aerox 5 is built around.
Product Info
The Aerox 5 launched in 2022 as the multi-button member of the Aerox lightweight line. The Amazon.co.jp listing referenced here (ASIN B09W19PZFF) showed ￥11,735 when captured on 26 May 2026.
Prices move with sales and exchange rates, so check the product page for the current figure before buying.
The other reference is an eBay US listing at $114.88, captured 10 July 2026.
That is clearly above the domestic price and looks like an overseas seller listing. Once import duties, shipping and warranty logistics are factored in, buying domestically is the more sensible route when stock is available.
Reviews stand at 847 with a 4.3-star average (captured May 2026).
At that sample size, a 4.3 suggests no widespread early-failure or fundamental design defect.
Averages still reflect who chose to buy it, though, so they cannot tell you whether the shape suits your grip.
Warranty is the standard one year from the manufacturer. The package centres on the mouse and its integrated cable; no replacement feet or extra accessories are included.

Best Use Cases
MOBA and MMORPG players — ideal if you want skills and items on side buttons but do not want the weight and misclick risk of a twelve-button mouse. Nine buttons is about right for the actions you need without lifting a hand off the keyboard.
Long-session players — 66g starts to matter past the three-hour mark, in wrist and forearm fatigue. The IP54 rating is genuine insurance if your hands sweat or your desk collects dust.
People who choose wired deliberately — forgotten charges, lost dongles, congested 2.4GHz bands.
Avoiding all of that is still a rational reason to buy wired in 2026.
Players who switch genres — one mouse that covers FPS and MMO reasonably well beats swapping devices between sessions.
Things to Check Before Buying
Skip it if perforated shells bother you. The honeycomb is the price of the weight, and no spec sheet tells you how the hole edges will feel against your palm.
Try one in a store if you can. IP54 helps, but a water-resistance rating never means "safe when submerged".
Skip it if you want 8,000Hz polling. 1,000Hz / 1ms is standard for wired, but current-generation competition mice go further.
On a high-refresh setup this is where the Aerox 5 shows its age.
Do not buy on the 18,000 CPI figure. It looks weak beside mice claiming 26,000 or 35,000 CPI, but the usable range is around 800-1,600 CPI.
Maximum CPI is almost meaningless as a purchase criterion.
It is a mid-tier multi-button mouse. Nine buttons will not hold a full MMORPG rotation.
Equally, a pure FPS player pays weight and money for buttons they will never press.
Treat every price as time-stamped. The ￥11,735 quoted here was captured on 26 May 2026.
This is a 2022 product, so successors and stock levels move the price significantly, and overseas listings like the $114.88 figure can sit far from the domestic price.
Listing metadata is sometimes wrong. Manufacturer and model-number fields on retail pages occasionally carry another product's data.
Confirm from the images and title that you are buying the wired Aerox 5 / 62401 specifically — the Aerox line includes wireless and lower-button variants, and some listings present them confusingly.
FAQ
Q. Are nine buttons enough for an MMORPG? A.
Enough for core skills and items, but if you want the full rotation on the mouse alone, look at a twelve-side-button model. The Aerox 5 assumes you keep using the keyboard.
Q. Does IP54 mean I can spill a drink on it? A.
No. It is splash and dust resistance, not waterproofing.
Wipe up any spill immediately and let it dry fully before powering it again.
Q. Do I need SteelSeries GG? A.
It works as a basic mouse without it, but button mapping, CPI settings and RGB all require GG. Treat it as effectively mandatory if you want the nine buttons.
Q. Will it work on PS5 or Xbox? A.
Console mouse support varies by title and is not an officially supported use case. Choose something else if consoles are your main platform.
Q. Is 66g actually light? A.
Clearly lighter than a ~100g multi-button mouse, though competition models now reach the 50g range. Within the category it is "lightweight-leaning standard" — reasonable given the nine buttons.
Q. Can I replace the feet? A.
It ships with PTFE feet but no spares. Plan on buying third-party feet in the matching shape if you want to change the glide.
