Summary
The Logitech M720 Triathlon has earned a devoted following among productivity users who run multiple devices, with many Reddit users reporting 4–6+ years of daily use. Sentiment is overwhelmingly positive, with the core appeal being its three-device switching, comfortable mid-size ergonomics, and strong price-to-performance ratio compared to the MX Master line. It sits in a sweet spot for users who need multi-device functionality but find the MX Master series too large or expensive. The main recurring frustrations are the degrading rubberized coating and long-term switch reliability issues like double-clicking and failed drag-and-drop, which tend to appear after 2–4 years of heavy use.
