Just like sitting in an office chair all day isn’t good for your health, using a traditional mouse for hours on end does a number on your body. Those small, repetitive movements and awkward hand positions take a serious toll on your wrist, forearm, and even your shoulder — which is why I switched to a trackball mouse many years ago.Not too long after I made the switch, though, a different kind of mouse started blowing up. Although the vertical mouse was first introduced by inventor Jack Lo back in 1994, it wasn’t until the launch of the Logitech MX Vertical in 2018 that they actually became mainstream.Maybe it was because this new device was part of Logitech's excellent MX Master Series, but once the MX Vertical hit store shelves, vertical mice were here to stay. More recently, the company released a cheaper, more compact version called the Logitech Lift. In the years since, other accessory makers have joined the fray, and these days you can find vertical mice from Acer, Anker, ProtoArc, Ugreen, and of course, Keychron.Since I was already testing out its new Q11 Ultra split keyboard, Keychron asked if I’d be interested in trying out its M5 vertical mouse. While I’ve used a trackball as my daily driver for over a decade now, I figured it was finally time to give a vertical mouse a shot. After using the Keychron M5 for the past month, I honestly wish I had sooner.Form follows forearm
