Product 2: Razer Viper V4 Pro
4.5

Grip texture and coating received strong praise for feeling matte, grippy, and secure, with one concern about long-term shine.

handedness options
Product 1: Logitech G305 Lightspeed
2.9

Handedness was mixed because the shell is symmetrical, but left-side thumb buttons make it less useful for left-handed users.

Product 2: Razer Viper V4 Pro
