Prior to official kick-off day, the TechPowerUp team was kindly invited to have a sneak peek around the ASUS booth. Brand-new Republic of Gamers (ROG) Harpe II Ace gaming mice were on full view (with black or white livery), sitting atop second-gen Sheath XXL mouse pads. The original ROG Harpe design was released over two years ago; as an Ace Aim Lab Edition. Last year, two spin-offs were introduced last summer: Harpe Ace Extreme and Harpe Ace Mini. ROG's freshest offering appears to utilize familiar internal components; most notably the cutting-edge AimPoint Pro optical sensor—very likely derived from Pixart's flagship PAW3950 model. Other mainstays include ROG's Optical Micro Switches (rated up to 100 million clicks) and SpeedNova 8K wireless system.

The ROG Harpe II Ace is built with a special and innovative bio-based nylon material, that contributes very little weight. A product placard advertises a total unit weight of 49 grams; only 2 g lighter than the ultra-premium Harpe Ace Extreme model. This $249.99 (MSRP) option features a fully CNC-machined carbon fiber top shell. The company has collaborated with Max "Demon1" Mazanov and other esport champions; thus refining the right-hand ambidextrous Harpe design for a new generation. Instead of using three or four skates, the Harpe II Ace is outfitted with two large chunks of rounded-edge pure PTFE. Gear Link—a web-based platform—grants access to hardware configuration; a massive plus point. TechPowerUp's pzogel has often directed criticism at the manufacturer's Armoury Crate software suite. A "lighter" and "less intrusive" package—called Armoury Crate Gear—was pushed out in recent times, but gaming mouse purists (largely) remain unconvinced.The Sheath II XXL mouse pad model is showcased as a lower temperature alternative to rival equivalents. As inspected by TPU staffers, ASUS ROG's peripherals section presents an infrared comparison video—displayed on a Flow Z13 demo unit's display.The company claims that the Sheath II XXL's cooling fabric dissipates heat 18% faster than regular weaves.
