An elegant glass desk won't cause havoc with this Logitech MX Master mouse - its 8000 DPI sensor works on any surface. The buttons feel nice and tactile, but they are Quiet Click, so silent no-one will hear you working away. Scrolling with MagSpeed is accurate and nearly silent too. But the ridiculously fast scrolling is the real party piece. If you need to, you can fly from top to bottom of massive documents with just a flick. And for navigating Excel, there's a second scroll wheel for moving left-to-right. Good to know - It's not just pretty and comfy - this MX is totally optimised for Macs and even works with iPadOS - Reduce wrist ache - it's designed for more natural wrist postures and has optimally placed thumb controls - Customise buttons, build app-specific profiles, and turbo-charge your Mac's workflow with Logi Options+ - Flow lets you work on up to 3 Macs at once and you can even drag files between them - The crazy-good battery lasts up to 70 days and can quick charge to give you 3 hours in just 1 minute! - Many Macs don't have a USB port so this version is designed to work perfectly just with Bluetooth Please note: iPadOS does not support software-based functions such as Logi Options+ customisation.
