Adesso iMouse E70 2.4GHz Wireless Ergonomic Vertical Left-Handed Mouse

In this review the Adesso iMouse E70 is evaluated as a left-handed, ergonomic gaming-style mouse aimed at users who spend long hours at a desk and need a more natural hand position. The single biggest reason to buy is its vertical, left-handed design which reduces forearm twist while still providing gamer-oriented controls and a programmable driver. The review focuses on real use: setup over 2.4 GHz RF, adjustable DPI for desktop or gaming tasks, and how the mouse handles daily navigation and extended sessions.

Key Features

• Ergonomic Vertical Design: The left-handed vertical shape keeps the wrist in a neutral position to reduce strain during long computer sessions.
• 2.4 GHz RF Wireless: The included USB receiver provides a stable wireless connection and an on/off switch to preserve battery life when not in use.
• Adjustable 3-Level DPI: The 800 / 1600 / 2400 DPI switch lets users quickly change cursor sensitivity for precise work or faster tracking in games.
• Programmable Driver: The driver allows remapping of buttons and customization to suit productivity workflows or gaming macros.
• Design for Gamers: The button layout and switchable DPI make it suitable for casual and some competitive gaming where an ergonomic left-handed shape is needed.

Who It's For

The iMouse E70 is best for left-handed users with repetitive mouse use who want an ergonomic vertical design and the flexibility to tweak sensitivity for different tasks. It suits designers, office workers, and gamers who prefer a neutral wrist posture and need programmable buttons without a complex setup.

This is not the ideal choice for users who require Bluetooth connectivity or very high-end gaming features beyond a standard 2.4 GHz RF link and three DPI levels. Those who demand ultra-fast scrolling behavior under heavy continuous use may want to test scrolling performance first, as user feedback on scrolling speed is mixed.
