Packaging

Aside from the mouse, one finds a USB Type-A to Type-C charging cable, ROG Polling Rate Booster, wireless extender, wireless dongle, set of PTFE replacement feet, set of glass replacement feet, set of grip tape, cleaning kit, carry case, display stand, stickers, and quick start guide in the box.

Weight

My scale shows around 47 g (+/- 1 g), which is exactly in line with the weight cited by ASUS. For comparison, the Harpe Ace Aim Lab Edition weighs 54 g, same as the Razer Viper V3 Pro. An excellent weight.

Cable

The Harpe Ace Extreme comes with a paracord-like, braided charging cable (USB Type-A to Type-C). Though visually nearly undistinguishable, this cable has different properties compared to earlier releases, and its flexibility is merely average, though playing while charging still is possible without feeling overly restricted. Its measured length is 1.75 m.

The charging cable also functions as an extension cable if used in conjunction with the wireless extender. The wireless extender can be used to keep the distance between dongle and mouse as short as possible. The wireless extender has a metal clip that can be used to clip the extender to the mousepad.

Feet

The feet on the Harpe Ace Extreme are pure PTFE (Teflon) feet with slightly rounded edges. They are of average thickness and glide very well. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. Since the front feet recessions are larger than the feet themselves, larger-sized feet may be installed, including the sets of PTFE and glass replacement feet included in the box.
