The mouse that changed my workflow
The Flow 2.0 feature alone is worth the price. I control my MacBook, Windows PC, and Linux workstation with one mouse. Copy-paste across computers works flawlessly. The haptic scroll wheel is addictive — I miss it when using any other mouse.

I switched from a standard mouse and gained back hours. The gesture controls and app-specific profiles automate my most common tasks. Battery lasts months. The ergonomics eliminated my wrist pain. Best $149 I've spent on my desk.
The hardware is perfect — scroll wheel, tracking, ergonomics, battery all top-notch. But Logi Options+ is bloated and occasionally glitchy. Once you set it up, it works fine, but initial configuration is frustrating. The mouse itself is a 10/10.
