Microsoft Bluetooth Ergonomic Mouse
Score: 85/100
Razer DeathAdder V4 Pro Wireless
Score: 86/100Rankings

The Razer DeathAdder V4 Pro is a high-end wireless gaming mouse featuring a 45K DPI sensor and ultra-low 8K polling for esports performance. Its large ergonomic shape and reduced battery life at max polling are notable trade-offs. Ideal for medium-to-large-handed competitive gamers who prioritize precision and speed.

The Microsoft Bluetooth Ergonomic Mouse combines a comfortable right-handed shape, long 15-month battery life, and three programmable buttons for productivity. Its trade-offs include lack of left-handed support and no onboard memory for settings. Best for right-handed office workers who value ergonomics and multi-device convenience.
