I am curious about the vertical mouse and its benefits – the older I get, the more I become concerned about carpel tunnel. Now that I've transitioned to a WFH set-up – this vs the MX3 was the toss-up. I think either or, you won't really go wrong.
This is quite nice, quick to get used to and nicely weighted. The software needs improvement – from a gamer, a more defined DPI stat, less a percentage scroller, would be nice. I would recommend it for productivity – definitely not for gaming. Buy on sale.
