What Mouse Does Muz Use?

Muz's mouse history

The history covers five periods and four switches, and he has not gone back to any earlier model.

The standout is the Razer Viper V3 Pro Black: 20.9 months (1.7 years), from May 2024 to February 2026. It is the longest period in the history.

The other earlier periods are short. The Razer Deathadder V3 Pro Black lasted about 21 days, the ZOWIE U2 2.0 months and the Lamzu Maya X Pink 1.6 months.

The Razer Viper V4 Pro Black has been his mouse since April 2026, replacing the Maya X Pink.

Mousepad

He plays on the Artisan Ninja FX Zero Soft Black, which he has used since October 2024. Before it came the Razer Gigantus V2 (February to March 2024) and the 4D Gaming TESSERACT (March to October 2024).

It is a cloth pad with stitched edges and a Control-Oriented overall glide. At 3 mm it is thin. The static friction of 41.3 and dynamic friction of 2.51 describe a surface built for stopping control rather than maximum glide.

The X/Y glide difference is 11.2%, so horizontal and vertical movement do not feel identical.

Mouse settings

In Fortnite he runs 1600 DPI with X and Y sensitivity both at 3.5%.

The mouse is rated for 8000 Hz polling, but his setting is 1000 Hz.

The other four values are multipliers of the X/Y sensitivity, not separate speeds. Targeting (49.6%) and Scope (50.0%) both run just under or at half the X/Y speed. Building and Editing sit at 100.0%, the same speed as X/Y, so there is no separate slowdown or boost for those modes.

Should you buy Muz's mouse?

The Viper V4 Pro Black is a wireless, ambidextrous mouse at 49 g, 12.7 cm long, 6.4 cm wide and 4.0 cm high. It uses the Focus Pro 30K sensor, Razer Optical Gen-4 switches and supports 8000 Hz polling. The shape suits anyone who wants a low-profile, symmetrical-format wireless mouse at a very low weight.

The alternatives trade a little weight or size:

• Razer Viper V3 Pro Black: 5 g heavier, with the same length, width and height. It has the Focus Pro 35K Optical Gen-2 sensor and a 67.6 g button force. 11 pros use it now.
• ASUS ROG Harpe Ace Extreme: 2 g lighter, with the same length and width and 0.1 cm lower. It is the lightest mouse in this comparison at 47 g. 1 pro uses it now.
• ASUS ROG Harpe Ace 2 Black: 1 g lighter, 0.1 cm shorter and 0.1 cm narrower, with the same height. It is the shortest and narrowest of the four. 2 pros use it now.

The V4 Pro sits between the two ASUS models and the V3 Pro in weight. All three alternatives also offer 8000 Hz polling, wireless connection and an ambidextrous shape.
