Verdict: The AngryMiao AM Infinity .97 is a premium, genuinely lightweight gaming mouse whose magnetic, hot-swappable battery is more meaningful than its headline 8K polling rate. It weighs 47 g in wireless use, can run at 39 g when wired without the battery, and combines a PAW3950 sensor with tri-mode connectivity. The design is especially compelling for claw and fingertip players who dislike charging interruptions. Its high price, basic web software, absent DPI button and sharply shorter battery life at 8K make it a specialist purchase rather than an automatic recommendation.
What the AM Infinity .97 is
The AM Infinity .97 is the smaller successor-style variant in AngryMiao’s Infinity line. Its defining idea is a magnetic 340 mAh battery that you can remove and replace instead of waiting for an internal cell to recharge. A spare battery can sit in the wireless receiver, which also functions as a charging dock. That arrangement addresses the most practical objection to very light wireless mice: a depleted battery normally means adding a cable or accepting a heavier replacement.
The mouse uses a magnesium-aluminum alloy hollow exoskeleton over a PC base. Angry Miao lists a flagship PixArt PAW3950 sensor with a maximum 30,000 DPI and dual 8,000 Hz polling over both cable and 2.4 GHz wireless. Those are high-end specifications, but the battery system—not the maximum DPI number—is the feature that changes how you use the mouse day to day.
Angry Miao’s own description calls the PAW3950 performance “unprecedented hardware performance.” That is marketing language, not an independent measurement; the practical results depend on your game, display, USB setup and chosen polling rate.

Weight and build: why the numbers matter
At 47 g with the battery installed, the .97 sits firmly in the sub-50 g class while remaining a usable wireless mouse. Removing the battery for cable use lowers the mass to 39 g, a useful option for players who value the lowest possible weight during a tournament or a long aim-training session. RTINGS specifically notes that wired operation without a battery pack is supported; the 39 g figure is therefore a real operating mode, not a theoretical shell weight.
The shell combines a magnesium-aluminum alloy frame with a plastic-composite (PC) base. Metal keeps the exoskeleton rigid while the hollow structure removes material that a conventional solid shell would retain. This construction is the reason the mouse can carry a replaceable cell without becoming heavy, although users who prefer a dense, fully enclosed body may find the open exoskeleton unfamiliar.
The rear cover is included in the 123.2 mm overall length. Angry Miao also publishes 115 mm without that cover, so comparisons based on a ruler can differ depending on which dimension is used. Width is 62 mm and height is 38.6 mm. These measurements, together with the shorter .97 mold, explain why it feels more compact than the original Infinity rather than simply being a lighter version of the same shape.
Shape and grip suitability
Angry Miao positions the .97 as a claw- and fingertip-grip mouse for smaller hands. The mold is described as 3% smaller than the original Infinity. A shorter rear section and compact footprint let claw users anchor the heel of the hand without forcing the fingers too far forward, while fingertip users can make larger corrections with less shell to move.
Independent hands-on observations are less restrictive than the marketing target: reviewers found palm use possible as well. That does not make the shape universally comfortable. Palm comfort depends on hand length, finger proportions and how far back you hold the mouse. The safest interpretation is that claw and fingertip are the intended starting points, while palm grip is a personal fit rather than a guaranteed strength.

- Choose it for claw grip if you want a short body that supports a raised palm and bent fingers.
- Choose it for fingertip grip if low mass and unrestricted fingertip movement matter more than a full palm shelf.
- Test before buying for palm grip because the compact .97 shape may leave larger hands without enough rear support, even though some reviewers could palm it comfortably.
Sensor and 8K polling performance
The PAW3950 is the mouse’s tracking engine, with sensitivity configurable up to 30,000 DPI. Very few players need anything close to that ceiling; the value is the sensor’s modern high-end platform and the ability to select a normal gaming sensitivity without operating near its limits.
Polling can be set as high as 8,000 reports per second over a cable or 2.4 GHz wireless link. PC Gamer lists an adjustable range from 125 to 8,000 Hz. Lower settings reduce processing and radio work, while 8K can reduce the time between reports on a fast display. The benefit is most visible in high-refresh competitive play and smooth cursor movement; it is not a universal increase in accuracy.
Neither the manufacturer specifications nor the cited reviews establish an independent latency benchmark for every mode. Treat 8K as a capability, not a promise that every computer will show a measurable improvement. A high report rate also creates more USB and CPU activity, so check for stable frame times and a compatible game before making it your default.
The swappable battery system
The 340 mAh battery attaches magnetically and can be exchanged for a charged spare. The supplied receiver doubles as a charging dock, allowing one cell to power the mouse while another is ready. This is the central advantage over a conventional sealed-battery ultralight: you can restore wireless use by changing the cell rather than connecting a cable or waiting for a recharge cycle.
Angry Miao’s runtime figures vary dramatically with polling rate:

| Polling setting | Claimed runtime | What the figure means |
|---|---|---|
| 8,000 Hz | Up to 30 hours | Manufacturer’s maximum estimate; actual time depends on usage and radio conditions |
| 1,000 Hz | Up to 165 hours | Manufacturer’s maximum estimate at the lower report rate |
| Other settings | Not stated | No additional runtime figures are provided in the cited material |
That table is why “infinite battery life” is an overstatement. With two cells and a dock, downtime can be close to zero, but each individual battery still has a finite charge. At 8K, the quoted 30-hour ceiling may mean charging or swapping every few days for a heavy user; at 1K, the 165-hour claim is much closer to a set-and-forget schedule. These are manufacturer claims rather than a standardized independent battery test.
How to use the battery arrangement
- Install a charged magnetic battery in the mouse for wireless play.
- Place the spare cell in the receiver’s charging dock so it is ready for the next swap.
- Use the 2.4 GHz receiver for the lowest-latency wireless mode, Bluetooth for compatible general-purpose devices, or USB-C when you want a wired connection.
- If the battery is depleted, remove it and substitute the charged spare; connect the mouse by USB-C while you recharge or prepare another cell if necessary.
The exact charging indicator behavior and charge time are not specified in the available product information, so do not assume a particular LED pattern or recharge duration.
Connectivity and everyday setup
USB-C, Bluetooth and 2.4 GHz give the .97 three connection choices. For competitive games, 2.4 GHz is the relevant wireless mode because it supports the advertised 8K polling. Bluetooth is useful when you want to move between compatible computers or preserve the receiver for another setup, but the available specifications do not state its maximum polling rate.
A practical first-time setup is:
- Connect the receiver to the computer and place it in a position with a clear line to the mouse.
- Insert the charged battery and switch to 2.4 GHz mode for gaming, or connect the USB-C cable if you want wired operation.
- Open the web-based AM Master interface to select polling rate, DPI, button assignments, debounce behavior, sensor height and RGB settings.
- Start at a moderate polling rate, verify stable behavior in your game, and raise it only if your system remains smooth.
- Keep the spare battery in the dock so the swap remains faster than a full recharge.
Because the companion control panel is web-based, browser compatibility, firmware version and the current AM Master implementation can affect the setup experience. The cited reviews characterize the software as basic rather than unusually deep.
Buttons, switches and controls
The store specification lists seven buttons. Main clicks use TTC Orange Dot Optical Micro-Switch V2 units, while the middle button has an independent switch. Optical main switches avoid the electrical contact arrangement used by traditional mechanical microswitches, but the available material does not provide a rated click lifespan or a measured click-force curve.

Button assignments, debounce, DPI, sensor height, polling rate and RGB are software-controlled. There is no dedicated DPI button. Players who change sensitivity frequently will need to assign another button or open the configuration interface, while players who set one sensitivity and leave it alone may never notice the omission.
Software limitations to expect
The AM Master web interface covers the essential controls, but TechRadar’s review calls the companion software basic. That means the mouse has the settings needed to tune tracking and buttons without promising the extensive profiles, automation or visual customization found in some larger ecosystems. Treat the web interface as a configuration utility rather than a full peripheral-management suite.
Before relying on a tournament profile, confirm that your preferred DPI stages, debounce value, sensor-height setting and RGB state persist after closing the browser or moving to another computer. The cited information confirms that these options exist, but it does not establish how many onboard profiles are stored or how every setting behaves offline.
How it compares with other ultralight mice
The .97’s meaningful differences are easier to see by category than by a single specification race. Mainstream alternatives such as the Razer Viper V4 Pro or Logitech G Pro X2 Superstrike may appeal if you prefer a familiar molded shell or a different software ecosystem, but the supplied material does not provide directly measured, like-for-like specifications for those models. The table therefore focuses on the decision axes established for the .97 and identifies where a comparison is not stated.

Price and value
TechRadar and PC Gamer reviewed or listed the mouse at $189. Angry Miao’s store showed a $159.99 sale price against a $179 regular price when checked in 2026. Those figures are time-sensitive and can change by region, tax, shipping and promotion, so verify the current price before ordering.
At the higher price, you are paying for the magnesium-alloy construction, 8K wireless capability and the spare-battery workflow, not simply for a lighter shell. The value improves if you would otherwise buy replacement mice because of battery wear or regularly play long sessions at a desk where swapping cells is convenient. It is harder to justify if you use 1K polling, never run out of battery, or need advanced profile management.
Strengths and compromises
What it does well
- Very low mass in both wired and wireless configurations.
- True 8K polling over cable and 2.4 GHz wireless, paired with a PAW3950 sensor.
- Magnetic hot-swappable battery removes most charging interruptions when a spare is available.
- Tri-mode connectivity covers competitive wireless, Bluetooth and USB-C use.
- Compact shape gives claw and fingertip users a purpose-built option.
What to consider before buying
- Premium pricing is high for a mouse with basic companion software.
- Wireless runtime falls to the manufacturer’s “up to 30 hours” at 8K.
- No dedicated DPI button means sensitivity changes require a reassigned control or software.
- Palm comfort is hand-dependent despite some reviewers managing a palm grip.
- Manufacturer battery and polling figures are claims, not independent standardized measurements.
Who should buy the AM Infinity .97?
Buy it if you want a sub-50 g wireless mouse, use claw or fingertip grip, and see a replaceable battery as a practical reliability feature. It is particularly suited to players who alternate between 8K for competition and 1K for longer battery life, or who keep a charged spare ready in the receiver.

Final assessment
The AM Infinity .97 is a technically ambitious ultralight whose magnetic battery solves a real problem more effectively than another incremental DPI increase would. Its 47 g wireless weight, 39 g battery-free wired mode, PAW3950 sensor and 8K wireless polling put it among the most specification-heavy lightweight mice. The compromises are equally clear: premium and fluctuating pricing, limited software depth, no dedicated DPI button and a manufacturer-rated 8K runtime of only up to 30 hours. For the right claw or fingertip user, the ability to swap batteries can justify the cost; for everyone else, the feature is impressive but not essential.
