Grasping the mouse, you’ll find that the base is high enough that the ring and pinky finger may lie against the side of the mouse while the index and middle finger can sit on the recessed grooves, the thumb lying in the anti-slip rubber groove. When used while slouching, well, just don’t do it unless you really hate your hand. When used with a low-friction mouse pad, it literally feels as if your hand is free flowing across the desk. Combine this with the lack of pressure on the wrist when used properly, and I must say that this is by far the most comfortable mouse I’ve ever used. You see, with the angled wrist, it’s actually easier to move the mouse from place to place by using your arm and not your wrist and fingers, as I have typically done with ordinary mice. I found it took about 20 or so minutes of continual usage before I was accustomed to the design. So how well does this ergonomic design work? Well, like anything radically different, it takes some getting used to. Users with adjustable chairs may find it beneficial to adjust the height of the armrest to help their elbows keep a 90-100° angle so that the wrist is properly lifted. When sitting back for watching DVDs on my computer, I found that my wrist found it’s way back onto the desk more easily than if I were sitting upright, and as such the mouse was actually more painful to use than a regular mouse due to the increased height and associated strain on the carpal tunnel. Users will find that such a comfortable position is only attainable when having a good sitting posture, and that means no slouching or having the mouse at an inconvenient height. Microsoft solidifies this by including a leaflet and sticker that initially covers the USB plug, instructing you to rest your hand vertically to the right of the mouse and let your hand fall into place, ensuring that your wrist remains lifted from the mouse pad. This is more or less the position your hand will assume when grasping the Natural Wireless Laser Mouse 6000 – a loose grasp without tension, and utterly comfortable to use assuming your seating posture is correct. Now raise it straight in front of you, leaving your fingers relaxed and not tilting your wrist. Stand up, and let your right arm go limp. Additionally, a near 45° angle keeps the angle of your wrist in a more natural position.
Whereas those mice were asymmetrical with a slight arch, thumb groove and buttons, the Natural Wireless Laser Mouse 6000 takes this several steps forward by shortening the base and raising the height of the mouse enough to keep your wrist off the table entirely. Microsoft’s first “Natural” entry into mice differs greatly from traditional mice, and even from other right handed mice including Microsoft’s own IntelliMouse Explorer and Logitech’s MX line of high end mice such as the MX Revolution.
