Logitech Lift For Mac Vertical Ergonomic Mouse The vertical ergonomic mouse for Mac, designed for all-day comfort. The optimal 57° angle of the Lift for Mac puts your hand in the so-called 'natural handshake position. This reduces the strain on your wrist all day long and puts your arm and upper body in a more natural position. Rest your hand on a softly textured grip, with easy-to-reach buttons that let you work all day without lifting a finger. There’s even a comfortable thumb rest. With a more relaxed upper body, your mind can focus on the things that really matter. Stay zen from morning to night with whisper-quiet clicks and a smooth-gliding, silent scroll wheel that adjusts to the lightest touch. The organic silhouette of Lift for Mac fits small to medium hands like a glove, custom designed and sculpted by Logitech’s team of ergonomics and design experts. With speed and precision scrolling modes, the SmartWheel lets you breeze through your work, editing line by line or flying through documents. Easily connect up to three macOS or iPadOS devices via Bluetooth Low Energy and enjoy two years of productivity.
