Review on 🐭 Evoluent VMDMW VerticalMouse D: Wireless Ergonomic Mouse for Right-Handed Users - Original VerticalMouse Brand (2002) by Jacob Richmond

I've been using the Vertical Mouse 4 for over a decade and I love it. The vertical mouse C did not have a scroll wheel (the standard for all mice in existence). Now this vertical mouse is D. Ergonomics and size are great. However, it grinds across a perfectly flat, smooth mouse pad or table and makes an annoying grinding noise. The tracking isn't up to par, especially on darker surfaces where it doesn't work at all. Such a shame.
