By skyforbes There’s something about the AM Infinity that just screams future tech. You don’t even have to plug it in — one glance and you know this isn’t your regular gaming mouse. The body lines look like they were sketched in the same room where Lotus cars are born: sharp, bold, and unapologetically different. Every angle feels calculated, every curve has a purpose.
But the real kicker isn’t just how it looks — it’s how smart it feels once you start using it. Angry Miao somehow managed to mix luxury design with a genuinely useful feature that makes daily gaming and productivity smoother than ever. It’s one of those rare cases where style doesn’t just meet function — it enhances it.
You’ll see what I mean in a second.

Unboxing
Shape and Grip
The AM Infinity surprised me with how natural it felt in my hand. I’m used to smaller shapes like the Razer Viper Mini or the RAWM SH01-Pro, but those always forced me into a tighter claw. Here, the slightly wider body gave me more room to breathe. With my 21×12 cm hands, I could claw, fingertip, and even palm it without that awkward “falling off the back” feeling. The only thing worth noting is the hollowed-out metal shell — it gives extra grip and keeps the weight crazy low, but it also means there’s less contact with the palm (the hump is pushed towards the back). The side curvature is flat, and the front flare is slightly outward.
During really long sessions, I noticed the right side of my palm getting a little numb because of that reduced support. For medium-sized hands, I think it will fit basically any grip style.
And bigger hands like mine? I’d say yes, it works surprisingly well. The only group that should think twice is small-handed users — the extra width might feel a bit too much to handle.
Bottom line? Medium to large hand users should be able to palm, claw, or even finger tip it.
Build Quality and Design
The AM Infinity looks like a sports car that somehow became a mouse — more Lotus concept than everyday Logitech. The magnesium frame gives it this cold, solid “engineered” feel, not the usual plastic toy vibe. It’s definitely on the extravagant side, the kind of design you remember after seeing it once. But nothing here feels random. All those cuts and curves have a purpose, especially the smart ball-catch system for swapping batteries (more on that later).
At first, I was a bit worried that an open-shell mouse would flex or feel fragile, but mine is rock solid — no creaks, no wobble, nothing. The only trade-off is obvious: dust and tiny crumbs can sneak inside if you’re not careful. Still, it’s a piece of gear that looks and feels like it came from a few years ahead of us.
One thing I missed: there’s no DPI button, so you have to go to the software every time, or you will have to bind it to one button (but that’s not optical).
Bottom line? Exceptional build quality meets a fancy design.
Buttons and Clicks
- Primary switches: custom TTC Orange Dot Optical V2 on M1/M2. Optical, 100M-click rated, marketed for “mechanical-grade” tactility.
- Encoder (scroll wheel): the exact model isn’t officially published anywhere I could find, but it looks like a TTC Dustproof Gold encoder by name, but this isn’t corroborated by AM docs.
The main clicks are tuned for a sharp, consistent click feel and long-term reliability, and they definitely deliver. The main clicks feel quick and responsive without any wobble up front. The side buttons deserve praise, too. They are unusually large, easy to reach, and give a strong tactile response that makes them great for fast actions in games.
There is one issue I found with my unit. The rear part of the right-click shell is so light that sometimes simply resting a finger there causes an accidental click. Angry Miao had some quality-control quirks in earlier products, so I really hope the next batch tightens this up and brings the clicks to perfection.
As for the scroll wheel, it feels like a tactile TTC design, though Angry Miao has not officially disclosed the exact encoder model. One review mentions a TTC Dustproof Gold encoder, but there is nothing confirmed in official sources yet. I will continue hunting for teardown photos or component markings to verify the specific part used.
Bottom line? Small issue with one of my main clicks, but overall they are tactile and crispy.
Weight, Coating, and Skates
With the battery inside, the AM Infinity sits at about 49 grams, and it drops to roughly 39 grams without it — so it’s already very light. Still, a part of me wishes they pushed it a little further into the low-40s range, because the rest of the design is so performance-focused that you can’t help wondering if there was still a bit of weight left to shave. At least the balance is right on point, with the sensor placed slightly forward at around 52%, so the mouse feels quick but still controlled.
There’s no coating here since it’s a magnesium shell, but honestly, it doesn’t need one. The cool metal surface actually grips the hand better than expected and feels great during longer play.
The skates are black PTFE — thin and not rounded, so they’re not exactly my favorite — but they get the job done well enough and are semi-controlled.
Bottom line? I wish the mouse were in the low 40s.
Software
There’s a web software (and a downloadable driver you need) available for this mouse, and that’s a great thing. However, there’s a lot to improve. First of all, the driver runs in the background even if I use the web version — that’s not what we gamers want, and that’s one of the reasons we hate Razer’s Synapse so much.
Second, the sensor is 3950, and it’s capable of many great things that have not been made available so far. Angle-tuning is not present; the same goes for angle-snapping or removing unnecessary DPI steps from your setup. And if a mouse doesn’t have a mechanical DPI button, it’s a hassle to go through all of them (I bound a button for it). I wish AM implemented some key combination for it, for example, Alt + Mouse4, to toggle among them.
But other than that, the software just does what it’s supposed to do: you can customize your polling rate, rebind keys, create macros, manage profiles, set LOD, etc.
You can also customize the key debounce time, which is always a plus, and do the same with Motion Sync.
The software is minimal, and I see a lot of room for improvement here. Hopefully, with the next mouse releases, Angry Miao will fix it.
Bottom line? Software is just ok, a lot of things should be added or improved.
Infinite Battery Life. Wait, what?!
The standout idea behind the AM Infinity is its swappable battery system — that’s where the whole “infinite” battery claim comes from. Sure, the slogan is a bit over the top, but the actual execution is genuinely smart. Swappable batteries aren’t new at all, but this is a much smoother take on the concept. The battery sits underneath the mouse, held in place by strong magnets. When it’s time to swap, you just press it out, hover the mouse over the spare, and click — the magnets snap the fresh one into position instantly. No covers, no fiddling, no cables. Just a quick pit stop and back into the game. And it works so well, and it’s so fun to do that, I instantly fell in love with it.
(You may wanna see it in action in my unboxing video that I posted a few paragraphs above.)
The magnets are no joke — once the battery is in, it stays locked in place without any wiggle. Charging happens through the 2.4 GHz receiver instead of a regular USB cable, which also avoids the usual interference issues you can get around USB 3.0 ports.
The AM Infinity features two units of 340 mAh, both are rechargeable within a few hours. And they last around 2 days of heavy use at 8k polling, and twice as long at 4k. The polling rate stays rock-steady, and the sensor keeps up without breaking a sweat — fast tracking, quick acceleration, and no weird hiccups. Other rates like 1k and 2k are much better for your battery life in the long run, so you might wanna reconsider going above it. That’s just my honest advice as a reviewer because the profits from higher rates are not that impressive in general, though they do exist.
Bottom line? The hot-swap battery system works and feels great.
🔍 My verdict
This is a high-end, enthusiast-level mouse with excellent specs and build — it is for gamers who want premium materials and are comfortable with a niche design. But it’s less ideal for casual users, those on a tighter budget, or those who prefer traditional ergonomics (especially for smaller hands). Also, the “infinite battery” concept is clever but likely more about rapid battery-swap than truly never needing charging — so manage expectations even though I really love this concept.
Overall, my experience with AM Infinity was great — I’ve had very good results in every game I played, the sensor performance was flawless, the clicks were good, I loved the side buttons, and I never had to charge the mouse (you know what I mean). I also love touching this mouse; this magnesium alloy feels so nice and cool. It is really a pleasant mouse to hold.
My only nitpicks that I’d love to see improved it a broader software, perhaps a bit less weight, and the minor buttons flaw I’ve mentioned before. But would I recommend this mouse? This mouse is unique, so hell, yeah!
