The Logitech M720 Triathlon is worth a close look if you regularly bounce between a couple of computers and want a comfortable, long-lasting mouse that won’t nickel-and-dime you on batteries. The strongest praise from buyers centers on its effortless multi-device switching and genuinely impressive battery life. The main trade-off is a design quirk that can frustrate you until you tweak a setting: a sensitive thumb button that’s easy to press by accident.
According to the listing, the M720 can pair with up to three devices and lets you switch among them with a button press. In the supplied feedback sample, that feature is the clear headliner. Buyers describe moving seamlessly between a Windows laptop, a MacBook, and even a Fire TV device, often without ever needing the included USB receiver. The battery life also draws consistent appreciation. The listing promises up to 24 months on a single AA cell, and several long-term users in the sample report changing the battery only once or twice a year, which makes the mouse feel refreshingly low-maintenance.
Comfort and the scroll wheel get a lot of attention, though the wheel draws mixed reactions. Many users find the sculpted, rubber-coated shape fits a medium-to-large right hand nicely, with a thumb rest that reduces fatigue during long workdays. The hyper-fast scroll wheel is a highlight for flying through long documents, and the ability to switch to a precise click-to-click mode earns praise. However, a few people in the sample feel the wheel is a bit too loose for their taste, describing it as less substantial than wheels on some older Logitech models. It is not a universal complaint, but it is worth knowing if you prefer a tighter, more notched scrolling feel.
Before you buy, be ready to install Logitech’s software to get the most out of the mouse—and to sidestep its most mentioned annoyance. The sample shows a pattern: a hidden button on the left side, right where your thumb rests, is mapped by default to a Windows or system command. Several buyers say they triggered it accidentally during tense moments in games or just by gripping the mouse naturally, which yanked them out of what they were doing. The fix is simple. You can use the Logitech Options+ software to reprogram that button to do nothing, and many people say that solves the problem completely. A couple of Mac users in the sample note the software can occasionally lose its settings after waking a laptop from sleep, though others report no such trouble.
This article is based on a limited administrator-provided Amazon buyer-feedback sample and does not represent every consumer’s experience. The M720 Triathlon makes a lot of sense for someone who multitasks across several devices and wants a comfortable desktop mouse that practically sips battery power. If you are a dedicated gamer who needs ultra-high DPI or you strongly dislike installing companion software to customize buttons, you may want to pause and look at more specialized options.
