Packaging

Aside from the mouse, one finds a USB Type-A to USB Type-C charging cable, wireless extender, wireless dongle, set of grip tape, set of replacement feet, quick start guide, warranty guide, carry pouch, and several stickers in the box.

Weight

My scale shows around 54 g (+/- 1 g), which is exactly in line with the weight cited by ASUS. Compared to the Razer Viper V2 Pro, the Harpe Ace manages to weigh 4 g less while being larger and featuring basic RGB lighting, and weighs 2 g less than the much smaller Pulsar X2, which has neither RGB nor a full bottom plate. An excellent weight.

Cable

The Harpe Ace comes with a paracord-like, braided charging cable (USB Type-A to USB Type-C). There is no anchor at the mouse-end of the cable, so it may come loose during use, although this is unlikely, given how tight it fits. In terms of flexibility, the cable is very similar if not identical to the charging cables of the ASUS ROG Keris Wireless or Gladius III Wireless. Accordingly, the Harpe Ace can be used as if it were a wired mouse with barely if any perceivable difference in terms of handling compared to an exclusively wired mouse. The cable has a measured length of 2 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. A storage compartment for the wireless dongle is located on the underside of the mouse.

Feet

The feet on the Harpe Ace 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. Curiously, only the front feet have indents for easier removal.

ASUS ROG Hone Ace Aim Lab Edition

Along with the ROG Harpe Ace Aim Lab Edition, ASUS also releases the ROG Hone Ace Aim Lab Edition mouse pad. The Hone Ace is a non-uniformly black cloth pad using a "hybrid" surface said to feature near-perfect x and y-axis uniformity, providing a blend between speed and control properties. The surface coating is said to repel water, oils, or dust. At a size of 508 mm x 420 mm and a thickness of 3 mm, the Hone Ace also comes with stitched edges and a non-slip rubber base. As part of the integration with Aim Lab, the Hone Ace has ruler markings at the bottom of the pad, which may serve multiple functions, such as conveniently measuring actual CPI or being used in specific Aim Lab scenarios. The ROG Hone Ace Aim Lab Edition is available for $39.99.

Aim Lab

Speaking of Aim Lab, within Aim Lab one can access the settings optimizer, which consists of several trials supposed to help one determine sensitivity, CPI, or suitable settings for angle tuning and lift-off distance. While the first scenario is accessible regardless of which mouse is connected, the latter three scenarios are exclusive to the Harpe Ace and only become available after the first one has been successfully finished. This is curious in that the first and second scenario essentially do the same thing. Having tried all four trials, I can confidently say that none of them are particularly useful, even for beginners. Furthermore, a specific scenario for the Hone Ace pad called "Aim Lab X ROG 360" exists, which relies on the ruler markings on the mouse pad. Unfortunately, the purpose of this task eludes me entirely.
