Review on Perixx PERIMICE-713L Wireless Ergonomic Left Handed Vertical Mouse: 6 Buttons, 3 Level DPI – Black by Kwame Bandepalli

Good left vertical mouse. Its shape is identical to many other right-sided upright mice, only flipped to the other side, so it's already proven from an ergonomic point of view. I also have a few right-handed versions and they work really well too. A small problem, at least for me, is related to the button configuration. The top button is the "left" button and the bottom button is the "right" button. This means that if you previously used a left-handed mouse, you no longer need to change the mouse configuration on your computer to press the primary mouse button. Your left index finger is the "primary" button from the start. That's a plus for many, but not for me. I'm used to having a left and right mouse on the same computer so I can use both hands equally to avoid pain. Since it wasn't practical to swap the buttons every time I wanted to use a different mouse, I keep the default settings, which means the left button is always the "primary" button, even for my left mouse. Now I can't handle it anymore. I'm hoping this is programmed with the mouse rather than choosing which button does what, then that would be ideal.
