After a week with the ROG Harpe II Extreme Edition 20, its shape and glide stood out most. The translucent shell and gold-plated details catch the eye, but it was in games that it convinced us most—enough to prefer it to our Logitech G PRO X2 SUPERSTRIKE. One major obstacle remains: its €250–300 price during our test.
Our test conditions
This unit was purchased by our partner Absolute PC. We used it for about a week, averaging four hours a day, for office work, Counter-Strike 2 and Battlefield 6. We used a ROG Scabbard II XXL Edition 20 pad and the mouse’s original feet.
We mainly played through the wireless receiver at 1,600 DPI and 8,000 Hz, with lighting off. The cable was also used for just under two hours, solely for office work. Our impressions reflect this daily use; we did not measure latency.
A finish you want to admire
As with the Azoth Extreme Edition 20 keyboard, the finish impressed us. The translucent black shell reveals the inside, with 24-carat gold-plated details confirmed by ASUS [1]. We really like the look, and the built-in lighting is a great idea: we even plugged it in at the end of the week just to enjoy it.
The packaging is also carefully designed, and the accessories seemed sufficient. ASUS lists a presentation box, receiver with extension, two-metre cable, grip tape, glass feet and a cleaning kit [2]. We tested the mouse as supplied, without adding grips or changing the feet.
The coating provides good grip, and we had no slipping issues. The translucent area does pick up some palm marks, but this is a minor cosmetic flaw with no effect on comfort.
A shape that immediately feels right
We hold the mouse with our palm resting on it and our fingers curled. In this grip, the Harpe felt more comfortable than our previous Logitech. The side buttons sit perfectly under our thumb without adjusting our grip. After several hours, we had no discomfort.
ASUS lists dimensions of 126.1 × 63.9 × 39.7 mm and a weight of 82 g [2]. In motion, though, it feels very light. Its effortless glide across the pad contributes greatly to that impression.
Effortless glide in games
On the Scabbard II XXL Edition 20, the original feet feel very different from our Logitech’s. Glide is extremely smooth, almost too free for our taste at first. Even so, we stayed in control from the start, with no real adjustment period in CS2 or Battlefield 6.
What we particularly liked was this ease of movement combined with a shape that suits us. We immediately felt comfortable gaming. This impression applies to the mouse-and-pad combination used in the test.
The Harpe has a ROG AimPoint Pro 65K sensor rated up to 65,000 DPI and supports 8,000 Hz both wired and wirelessly [1][2]. At our 1,600 DPI and 8,000 Hz settings, we saw no disconnections, irregular movement or missed clicks. The brief USB trial also went smoothly.
Pleasant controls
Left and right clicks feel light without being too soft. Repeated clicks are easy, and we triggered no accidental clicks, even while gaming. They are audible, but the sound did not bother us.
The wheel’s resistance suits us. Its side coating is comfortable against the finger, even when reached at an awkward angle in a game. The wheel click works as expected, and we noticed no unintended scrolling.
We liked the cable less. During office work, we could feel it affecting movement. We preferred returning to wireless freedom.
Easy settings and a week without charging
We used Armoury Crate to adjust sensitivity and lighting, both straightforward tasks. ASUS also offers browser-based configuration through Gear Link [1], which we did not try.
By the end of the week, before plugging it in, the battery had dropped by about 40 percentage points with roughly four hours of daily use. We played wirelessly at 8,000 Hz with lighting off and did not need to recharge during the week.
We eventually plugged it in to admire the LEDs, then used it for just under two hours of office work. The battery reading was taken before that charge. We did not test it to complete battery exhaustion.

Key takeaways
The Harpe II Extreme Edition 20 won us over in our first games. Its shape suits our hand particularly well, the controls are pleasant and it glides with little effort. The finish and lighting through the shell add visual enjoyment that we also appreciated during this test.
At the same price, we would clearly choose it over our Logitech G PRO X2 SUPERSTRIKE. But at €250–300 during our test, it remains expensive, even if the limited-edition premium seems understandable. It is more affordable than the keyboard in the same collection, but still a significant purchase.
Palm marks and the slightly intrusive cable are our only minor reservations. In wireless use, we found nothing that made us want to switch mice. Price is therefore the main obstacle. With Christmas approaching, all we can hope is that stock lasts until then!
