Evoluent VerticalMouse 3 Wireless Ergonomic Mouse USB 1200DPI Silver Black Retail Box

The shape of the mouse makes it comfortable to use, but it comes with a tradeoff. It's more difficult to move the mouse due to its large size and the weigh of the batteries. This isn't much of a problem for general usage after you get use to it. However, for fast-paced gaming, the mouse is slow to move.Batteries do last a long times. Even after three months with rechargeable batteries, the mouse is still running.

Had the 2nd gen of this mouse at work, bought the same one for home use. Brilliant design, good build quality. The new 4th gen looks even better.Unfortunately I dropped mine several times over the years, and this last time was the final blow, now it doesn't track properly anymore.I want to buy another one, but it's too expensive at the moment. Back to killing my wrist with the Apple mouse, and a weird MS trackball.

I've been using this wireless mouse exclusively for 7 months (bought it for $79), and I do like it for its superior ergonomics. But I find that the tracking isn't so great -- it sometimes takes a couple of tries to click on radio buttons or check boxes. It's a bit large & bulky, but that's mostly due to its vertical height. The worst part of it is that the mouse does not ship with a free driver for Mac. Basic functions work without a driver, but Evoluent doesn't provide a driver, and third-party drivers like USB Overdrive and SteerMouse cost $10 or more.
