If you spend £93 on a mouse, you want it to be a mighty fine one - and Evoluent's VerticalMouse 3 Wireless is worth every penny.

When we first met the Evoluent VerticalMouse 3 Wireless, we thought it was a gimmick.

First, the Evoluent VerticalMouse 3 Wireless is an odd-looking beast, somewhat resembling the dorsal fin of an obese shark. Second, it seems to be a solution in search of a problem - after all, how many of us have injuries from mousing?

But after climbing the inevitable learning curve required by a new way of performing a tried-and-true operation, we're converted. Grasping the Evoluent VerticalMouse 3 Wireless in a comfortable hand-shaking position, using its five well-placed buttons, and benefitting from its precise 1,200-dpi resolution, we've experienced comfort and control we never thought possible.

The reason for this added comfort is simple. With your arm at a more natural angle - that is, with your wrist at a right angle to your desk-your forearm's bones (the radius and ulna, for you medical types) and muscles aren't unnaturally contorted. The Evoluent VerticalMouse 3 Wireless's buttons are... well... vertical, so clicking them is accomplished by a gentle squeeze.

Not that the Evoluent VerticalMouse 3 Wireless is perfect. Despite the mouse's sky-high price, Evoluent doesn't provide an Apple OS X-compatible driver - which is a shame, considering that its Windows driver is chock-full of fine customisation features, such as the ability to toggle among three pointer-speed settings, click locking, and even an audio-visual break reminder.

Moreover, there's no left-handed version of the Evoluent VerticalMouse 3 Wireless available.

The Evoluent VerticalMouse 3 Wireless is a bit hefty, as well; with its two (included) AA batteries installed, it weighs a full 0.2kg. Some mousers may find this weight a literal drag, but we felt that it was an aid, as it helped keep the VerticalMouse from overreacting to the sideways clicking of its finger buttons.

The Evoluent VerticalMouse 3 Wireless's interference-busting 2.4GHz wireless signal is picked up by a USB dongle, solid black save for a blue LED that tells you when it's receiving a command. This compact 38x13x6mm unit won't block any adjacent USB ports, no matter how closely spaced yours are.

OUR VERDICT

Even if you're not already experiencing pain from the unnatural forearm rotation required by traditional mice, the Evoluent VerticalMouse 3 Wireless will provide comfort and control you never anticipated. Sure, it takes some getting used to, but the first person to use a steering wheel instead of a tiller probably required an adaptation period as well.
