> I'm curious, what are the advantages to using this over a regular mouse?

The advantages are probably similar to those of any vertical mouse: There's much less stress on the wrist, which is important if you're suffering from e.g. RSI.

But since in this case the mouse is also ambidextrous, you can switch hands, too. (-> Useful for ambidextrous people and, also, even less stress on the individual wrist.)

For a cheaper setup, I have a right-handed vertical mouse (Amazon $20 special) to the right of my keyboard, and a second left-handed mouse on the left, and I switch between them throughout the day. It makes my desk look a little silly, but it works great!

I've adopted a similarly-inspired setup with a tradtional mouse on the right and a touchpad on the left. I initially added the touchpad to assist with vertical scrolling on Mac OS, but now I move between the two depending on the task and it keeps my wrists happier.

Same setup here. Hoping for even more input devices in more places to spread the load. For instance there's also some folks building ergo keyboard with trackpads near the thumbs to replicate the MacBook experience of a trackpad below spacebar for the occasional pinch zoom or scroll. And having various buttons/knobs for specialized tasks would also be great.

Good idea.

Exactly that. It has a flip switch to swap the left/right buttons when you change hands, but I never use that as I'm used to thinking of right click as index finger and left click as middle finger on either hand.
