What Mouse Does Demon1 Use?

Demon1's mouse history

Demon1's history covers 16 periods, 15 switches and 7 different models since April 2023. He started that run on the G-Wolves Hati S+ 4K for 7.0 months, then moved between mice often.

The G-Wolves Hati S+ 4K is the constant. It has 6 periods and 5 returns, for 18.8 months (1.6 years) in total. The Razer Viper Mini Signature Edition has 3 periods and 7.0 months in total, including a 5.8-month stretch from May to October 2024.

Several models got only a short trial. The ASUS ROG Harpe Ace lasted about 12 days in its first period, and the Finalmouse Ultralight X Medium about 27 days. The Razer Viper V3 Pro Black ran for 1.4 months and the G-Wolves Hati S for 1.8 months.

The ASUS ROG Harpe Ace 2 Black has 2 periods and 11.6 months in total. Its first period ran from May to August 2025, followed by 5.2 months back on the Hati S+ 4K. The current period began in January 2026 and, at 8.8 months, is the longest single stretch on any mouse in his history.

ASUS's press release of May 19, 2025 says the Harpe II Ace was developed and tested with Demon1. He posted on X the same day that he had worked with ASUS on the mouse.

Demon1 uses the Yuki Aim x Demon1 Cloth pad, in use since July 2025 (15.1 months). It is a square 50 cm cloth pad, 4 mm thick, without stitched edges.

Before it, he spent 3.8 months on the ZOWIE G-SR-SE Rouge, from March to July 2025. That model is the longest-running pad in his history at 14.9 months, from November 2023 to February 2025.

The polling rate is set to 4000 Hz, although the Harpe Ace 2 Black supports 8000 Hz. Windows sensitivity is 4 and Raw Input Buffer is on.

Should you buy Demon1's mouse?

The ASUS ROG Harpe Ace 2 Black is a wireless, ambidextrous mouse at 48 g. It measures 12.6 cm long, 6.3 cm wide and 4.0 cm high. It has the ROG AimPoint sensor, optical switches and 8000 Hz polling. The symmetrical shape and low weight suit players who want a compact, light mouse without a left or right bias.

The alternatives are close in size and differ mainly in weight and sensor.

• Razer Viper V4 Pro White: 1 g heavier, 0.1 cm longer and 0.1 cm wider, with the same height. It uses the Focus Pro 30K sensor and Razer Optical Gen-4 switches, and 7 pros use it now.
• Razer Viper V3 Pro Black: 6 g heavier, 0.11 cm longer and 0.09 cm wider, with the same height. It has the Focus Pro 35K Optical Gen-2 sensor and a 67.6 g button force, and 8 pros use it now.
• ASUS ROG Harpe Ace Extreme: 1 g lighter, 0.1 cm longer, 0.1 cm wider and 0.1 cm lower, with the same ROG AimPoint sensor. 1 pro uses it now.

The Viper V4 Pro and V3 Pro cost some weight and bring a Razer sensor and switches. The Harpe Ace Extreme stays in the ASUS family at a slightly lower profile.
