When we say lightweight, we mean it. The ROG Harpe Ace Mini weighs in at 1.72 ounces, making it lighter than the Corsair M75 Air (and that one even has the very lightness in its name). Yet the Harpe Ace Mini still serves up more features than the M75 Air—the latter lacks RGB LEDs in its scroll wheel, for instance.
At 1.4 by 2.5 by 4.6 inches (HWD), the ROG Harpe Ace Mini is even smaller than the Corsair Katar Elite Wireless, which clocks in at 1.5 by 2.6 by 4.7 inches (HWD), and the ROG Harpe Ace Mini’s optical sensor is more sensitive, to boot. (The Harpe Ace Mini reaches a maximum of 42,000dpi; the Katar Elite Wireless can only hit 26,000dpi.)
Still, if you want serious flair, look elsewhere. As a wireless, lightweight esports mouse, the ROG Harpe Ace Mini has a minimalistic design by necessity. The body comes in either white or black, and the only flourishes are the RGB in the scroll wheel and the ROG logo. Meanwhile, the body has a smooth texture, and the sides have ridges to help your grip. There’s a USB-C port in front for charging or for a wired connection to your PC.

Like other mini-mice, the ROG Harpe Ace Mini is built for a claw-style grip—where the tips of your fingers hold the mouse body—but in testing, I found a palm-style grip works perfectly fine, too. A few rounds in 3D Aim Trainer, a tool many gamers use to hone their pointing skills, got me accustomed to the grip style (and I’m not a pro gamer, by any means). It didn’t take long to reach my average score, and, with some tinkering in the mouse’s control utility, gradually improve it.

One big caveat about the design, though: Lefties are out of luck. The ROG Harpe Ace Mini is a right-handed mouse, with buttons on the left, and no version is available for southpaws.

The mouse’s underside has a bit more going on than the rest of the body. Here, you’ll find the included USB dongle for the 2.4GHz wireless connection and a few controls: a button to cycle DPI modes, another to go into Bluetooth pairing mode, and a switch that lets you toggle among modes (Bluetooth, 2.4GHz wireless, and wired, the last of which doubles as the power-off setting). The bottom layout is nearly identical to the ROG Keris II Ace’s, down to the placement of the PTFE glide feet.

One thing to note about the USB dongle: It fits into a recessed enclosure without a locking mechanism (a magnet or a plastic clip). But I noticed enough of a friction fit to keep the dongle securely in place.
