Review on 🖱️ Wireless VerticalMouse 4 VM4SW - Ergonomic Right-Handed Mouse with USB Receiver (Small Size) by Evoluent - The Trusted Original VerticalMouse Brand for Over 18 Years by Megan White

I love this mouse but be sure to download the free software. The package doesn't tell you that. But the software is easy to find on Google and FREE. This allows you to program the buttons to do whatever you want. Three buttons that use your index, middle, and ring fingers. By default, the third button is "Right Click". But you can reprogram this with the software you download. But quite high. If you have a mouse under your desk on a keyboard stand, you'd better make sure you have the space before buying one. It's bigger than a normal mouse.
