ROG Harpe Ace Mini is the carbon fiber cousin of the ROG Harpe Ace Extreme, only with much less extra. It’s only 2 grams heavier than the 47-gram Ace Extreme, although it uses its minimal size instead of carbon fiber to keep it lightweight and uncomplicated to cast.
Aimed at professional FPS gamers and anyone who needs absolute precision in the games they play, the Harp Ace Mini uses the same huge 42,000 DPI ROG AimPoint Pro sensor to prove without a doubt that it’s not the mouse that’s what it’s after you miss all those headshots.
When held in my hand, the Harpe Ace Mini feels almost non-existent compared to the more MMO-oriented mice I’m used to. Compared to the Razer Naga Pro, it feels like it’s filled with helium. This is partly due to its compact size, but also to the lack of buttons. Where an MMO mouse might have double-digit buttons, the Harpe Ace Mini only has seven.
These are the standard two left and right buttons, a clickable scroll wheel, and two buttons on the right side and two on the bottom. They all have a satisfying click and most don’t sound too hollow, except for the one on the rear left which resonates a bit in the body. This is to be expected from a mouse with such a lamp, as there is almost nothing inside to absorb sound. And while the mouse may feel low-cost, the Harpe Ace Mini feels solid. Combine it with a attractive finish and it is sure to be a high-quality little rodent.

The Harpe Ace Mini is mostly ambidextrous, as long as it is semi-symmetrical. The side buttons are still on the left, so left-handers will have to exploit their little finger or whatever magic they exploit to cope with our right-wing-dominated world.
Some effort was certainly put into making the shape less curved on at least one side. This may be better for left-handers, but it means it’s less ergonomic in both cases. Compare it to something like the Logitech G502 X and its excellent ergonomics and it falls a little compact, but then some would prefer a less curved mouse design.

This thing is harmlessly compact, which makes it a great fit for my compact hands, although I imagine gamers with larger grippers would have a bit of trouble with it. Not much, but if you exploit a palm grip and have immense hands, you might want to think twice before buying something this compact. That said, the size actually makes this mouse even more portable.
Speaking of portability, I’m very impressed with the Harpe Ace Mini’s battery life. Using it for 12 hours on 2.4GHz Wi-Fi without charging or sleep, the charging indicator was still green.

Above: Tested at 1000Hz – the more irregular the dots, the worse the mouse tracking.
A week of 3-4 hour gaming sessions a day later and the charge was still over half full, even with the RGB lighting on. I don’t have enough time to drain the battery, but by my calculations it would take me at least four weeks to completely drain it at this rate.
As for the software needed, it requires Armory Crate Gear to play with button assignments, performance and power settings, but if you want to start using scenario profiles and designing your own macro settings, you’ll need to download the full version of Armory Crate & Aura Sync.
Buy if…
✅ You need the highest accuracy: ROG Harpe Ace Mini is truly an ace when it comes to accuracy. 8K polling speed and a fixed 24,000 dpi matrix provide an impressive advantage in accuracy.
✅ You don’t want to load a lot: The ROG Harpe Ace Mini’s battery life is impressive for something so lightweight. It lasts for weeks of work over Wi-Fi, and even longer if you choose to exploit Bluetooth most of the time.
Don’t buy if…
❌ You want to save money: There are plenty of precision mice on the market that fall well below the Harpe Ace Mini’s $130/£130 price tag. Wireless too.
❌ Do you prefer heavier mice: Harpe Ace Mini is incredibly lightweight. So lightweight that it’s barely noticeable in your hand, so it’s not intended for people who prefer heavier mice.
Honestly, the latter is a bit too much to access the macro options. Even the Lite version of the Gear requires quite a immense file to download and install, which is a shame, and I had a few issues with connection and setting changes that resulted in bugs. Having to restart your computer at several points to get the software to work isn’t a good look, although once it does work it does all the basic things well and the interface is nice and pristine.
In terms of performance, the ROG Harpe Ace Mini is a stellar mouse. There are no quibbles when it comes to accuracy, and consistent tracking points throughout the area show that this is a very precise rodent. Does it need to be so precise in everyday exploit? Probably not, but without compromising on weight for a more impressive sensor, it’s uncomplicated to appreciate the effort in this regard.
The Harpe Ace Mini performs very well when it comes to accuracy, and while its attempts to be ambidextrous does come at the cost of having more specific mouse ergonomics for right-handed people, I can really see it working for professional gamers and claw grabbers who prefer lightweight mice because under as long as they don’t mind downloading the massive Armory Crate software just to play around with macros. Thanks to its impressive battery life, anyone who wants to take the Harpe Ace Mini with them on the go will be ecstatic not to have to charge it for ages. Sure, there are cheaper wireless gaming mice with similar battery life, but few can match the impressive accuracy and weightlessness of the Harpe Ace Mini.
