Logitech Lift Ergo Vertical USB Optical Mice, Gray

Mouse is ergonomic and reduces stress and fatigue on my hands. I especially appreciate it comes in a left-hand option which is rare for high tech peripherals.

Finally, a true left-handed mouse! I'm cross-dominant (write left, throw right). Years of computer labs with the mouse on the right (and short cables) made me adapt to right-handed mouse use despite an early preference for a mouse on the left. I also found I could write notes to myself while mousing right, so I turned it into a win-win. However, decades later, I have some repetitive stress issues with my right wrist. I have a Logitech MX Ergo that has helped a lot, but it doesn't eliminate the problem. Luckily, my dominant left wrist is problem free! This mouse has been great to use. Having not used a mouse on the left for a long time, I sometimes confuse the buttons (to "right click" is actually to "outer" click). I would love a lefty version of the MX Ergo (hint!), but this is a great mouse too.
