ASUS’s Republic of Gamers (ROG) brand is turning 20 this year, and to celebrate, the company has launched a 20th Anniversary edition of its ROG Harpe II Extreme gaming mouse at Computex.
I was lucky enough to get the new Edition 20 mouse a couple of weeks ahead of the announcement, so I’ve had plenty of time to test it out in many a real-world situation. If the idea of a gold-plated mouse tickles your fancy, read on to see if it’s worth buying or not.
I’ve spent (nearly) my entire life gaming on a PC, and I’ve run through countless mice and keyboards. Add that real-world experience to my decade of testing and reviewing PC gaming hardware and accessories for Windows Central, and you can rest assured you’re only getting the facts.
ASUS had no input, nor saw the contents of this review, prior to publication.
How much does the ASUS ROG Harpe II Extreme Edition 20 cost?
The new ASUS ROG Harpe II Extreme Edition 20 mouse makes its debut at $259.99. It’s available for pre-order at both Best Buy and Newegg, and it’s expected to launch fully on July 19.
After launch, it will also be available at Amazon and Micro Center.
Considering the regular ROG Harpe II Ace, on which this special Edition 20 is based, costs about $170, you’re looking at roughly a $90 cost difference.
What’s in the box?
Alongside the ASUS ROG Harpe II Extreme Edition 20 mouse, the special display case has an ROG SpeedNova 8K receiver and extender, an ROG paracord, grip tape, extra mouse slides, stickers, a cleaning cloth, and documentation.
What I love about the ASUS ROG Harpe II Extreme Edition 20
The new ASUS ROG Harpe II Extreme Edition 20 is based on the Harpe II Ace that launched in late 2025. And just like its sibling ROG Azoth Extreme Edition 20 keyboard, it’s been given a makeover with gold accents, improved internals, and special anniversary branding.
Impeccable design that’s comfortable to hold
The Harpe II Extreme Edition 20 has been in use on my desk for gaming and for work for a couple of weeks, and it’s just as comfortable to hold at the start of the day as it is at the end.
Its sidewalls are lightly tapered to fit my fingers, and it has an ideal shape that rests firmly under my palm. It’s the perfect size for me, though I can see it maybe being a bit too big for those with smaller hands.
It’s just as comfortable to hold at the start of the day as it is at the end.
I was concerned with how slick the outer transparent shell can be when gaming, but ASUS has that issue covered with included grip stickers you can add if needed.
The mouse’s shell primarily has a semi-transparent black finish to help show off the internals. The outside is a little busy, what with all the extra ROG branding in honor of the anniversary, but that’s largely the point.
A gold-plated interior … with RGB lighting
The biggest aesthetic upgrade you get here comes in the form of an inner metal frame with real 24K gold plating.
The layered design helps give the mouse’s internals some depth beneath the transparent shell, and it’s finished off with an RGB 20th Anniversary ROG logo right in the center of the main internal plate. This logo connects to other RGB via Aura Sync.
Despite the new design, the mouse still only weighs 82 grams. It’s one of the lighter mice I’ve used, and although I’m now used to it, it would be nice to have adjustable weights like other high-end mice.
Scrolling, clicking, and gliding
The mouse’s black finish is nicely offset by a gold-colored scroll wheel and metal side buttons. I had no issues with any of the three inputs; the side buttons are perfectly placed for easy control with my thumb, and the scroll wheel is smooth but tactile.
ASUS uses its ROG Optical Micro switches below the main mouse buttons, making the mouse feel incredibly responsive. I also noticed while playing FPS games that it seriously drops the likelihood of double clicks, felt most when tapping fire on a rifle set to full auto.

These switches are also very durable, with ASUS claiming 100 million clicks before the switches wear out. Not bad.
Flipping the mouse over reveals stylized slides at the front and back of the mouse. These are made of Gorilla Glass for extra durability (nothing worse than your slides wearing away before the mouse is through), but they also make the mouse super smooth.
Here is where you’ll also find DPI and pairing buttons, as well as a toggle for 2.4GHz (via the SpeedNova 8K dongle), Bluetooth, or wired connectivity. There’s no dongle storage on the mouse; instead, ASUS says to use the (bulky) plastic carrying case when in transit.
The high-performance sensor you want for competitive gaming
I’m getting too old to have a real chance in competitive games, but I can say that the ROG Harpe II Extreme Edition 20 had me playing my best.
ASUS has its premier ROG AimPoint Pro 65K sensor on board, featuring a 65,000 DPI, adjustable lift-off distance (LOD) from 0.7mm to 1.7mm, maximum acceleration of 70g, and a max speed of 800 inches per second (IPS).

The mouse also lets me adjust its polling rate from 1,000Hz all the way up to 8,000Hz, which at the top provides just 0.2ms latency even when used wirelessly.
I didn’t really need it for my purposes, but a Zone Mode is available for competitive gamers. It quickly locks the mouse into the top settings so you can jump into a game after work without too many adjustments.
Battery life is excellent
ASUS uses something called dynamic wireless transmission power to boost battery life, and it claims the mouse can go for 195 hours with a 1K polling rate. I still haven’t hit that limit, but I’ve also not yet had to charge the mouse in the two weeks I’ve had it.
If you bump it up to an 8K polling rate, the battery life falls to about 37 hours. Still a respectable number that won’t have you reaching for a cable before every gaming session.
What I don’t like about the ASUS ROG Harpe II Extreme Edition 20
ASUS really did a great job of overhauling its flagship mouse for ROG’s 20th anniversary, and there are just a couple of nitpicks I’d like to mention.
One is the shell’s slick feel. Yes, ASUS includes grip tape, but adding it to the mouse kind of interferes with the overall sleek look.
Another nitpick is the lack of a USB garage built into the mouse. I don’t want to carry around a bulky plastic carrying case in a bag, and I also don’t want to just toss a dongle in there loose.
Finally, I can’t skip mentioning the price. I know this mouse is for ROG fanatics who want to help celebrate 20 years of gaming service, and I understand that its performance is superior to the ROG Harpe II Ace on which it’s based.
Still, asking $259.99 for one mouse is a bit steep, especially if you’re already dropping $600 on a matching keyboard.
Should you buy the ASUS ROG Harpe II Extreme Edition 20 mouse?
You should buy it if …
✅ You love the ASUS ROG brand and want to help ring in its 20th anniversary.
✅ You’re a competitive PC gamer who wants a high-performance, comfortable mouse.
You should not buy this if …
❌ You have particularly small hands or are left-handed.
❌ You prefer a heavy mouse or a mouse with adjustable weight.
Like the sibling ASUS ROG Azoth Extreme Edition 20 keyboard I reviewed, the new ROG Harpe II Extreme Edition 20 is a special accessory that’s not meant for the masses. That helps explain the price, at least.
If you are a ROG fanatic (or simply love the idea of a gaming mouse with some extra flash), I can promise that you’re landing one great device. Sure, it has a few little drawbacks, but overall, it’s a gaming mouse that has practically every high-performance feature I can think of.
It’s comfortable to hold (if a bit slick without grip stickers), the buttons respond as you’d expect and feel nice and snappy, and it has the right sensor and polling rate to keep up with even the fastest reactions.
