Logitech MX Vertical Mouse review - Critical Hit
If you do need one though, Logitech’s MX Vertical Mouse is undoubtedly the best of the lot. A combination of flawless wireless performance, intelligent features and solid design make it a worthwhile vertical mouse. Still I can’t help but feel that money would be better spent on Logitech’s own, superlative MX Master 2S.
