Logitech’s Signature Comfort M840 L and M850 L bring high-end ergonomics to a budget-friendly price point, but their main marketing feature might not be worth it.

Logitech has officially expanded its value-focused Signature Series lineup with the launch of the Signature Comfort Plus series, introducing the M840 L and the cushioned M850 L wireless mice. These models shift away from the symmetrical designs of older Signature mice, opting instead for a sculpted, right-handed ergonomic shape that closely bridges the gap between the mid-range M720 Triathlon and the premium MX Master series. Running on a single AA battery that lasts up to two years, they offer silent main clicks, horizontal scrolling shortcuts, multi-device pairing, and a customizable top bonus button. However, the standout addition, a built-in foam palm cushion on the M850 L, proves to be highly dependent on hand size and grip, offering minimal practical benefit for medium to large hands. Furthermore, the bonus top button remains entirely non-functional without downloading the proprietary software, posing a hurdle for corporate environments. This breakdown analyzes the build quality, real-world ergonomics, software dependencies, and overall value proposition to determine which version is truly worth your money.
