Just as a background, I have never really cared what mouse I used, until I started getting carpal tunnel. I tried the Anker Vertical Mouse and I have not had any trouble from my wrist since.
The wired and wireless mice are the same, it has a DPI button and works perfectly in Windows and Linux.
It does take a bit getting used to, as you will tend to move the mouse as you click. It is also pretty hardy, as being taller I tend to knock it over and onto the floor regularly. The worst that has happened so far is the batteries roll across the floor. it has an on/off switch on the bottom and a place to put the dongle.
The only gripe I would have is I wish the scroll wheel would be a bit more clicky.
They are actually a very good price for what you get. If you have issues with carpal tunnel I suggest trying one out.
