Hi Ozb,
Does anyone have any experience with vertical mice? Some examples include Logitech MX Vertical, Anker Vertical Mouse, J.Burrows Vertical Mouse. Are they more ergonomic than gaming mice or something like a MX master?
Currently using a Logitech G500s, it does get a little uncomfortable for long periods of use but not really painful. Interested in vertical mice but the MX vertical is quite pricey, cheapest I can find is $130 on ebay after discounts ($148 at Harvey Norman).
A couple of years ago I started having issues with my wrist and tingling feeling in my thumb so I got a Evoluent VM4R. It has helped heaps, however I had to change my habit as well, including switching to the left hand when my right hand doesn't feel right.
If you consider Evoluent brand, make sure that you try all their sizes to see which one works best for you. Their small size works for most people.
