The Bad: No programmable buttons
Operation
I've said this before and I'll say it again: Sometimes you don't want any bells and whistles. Sometimes you just want a mouse that will get your from Point A to Point B on the desktop, and you don't want to pay a premium for it. And in the case of road warriors and other travelers, sometimes you want this in a travel size.
The Genius Traveler 6000 delivers these things on all counts. It's a standard three-button optical mouse, with left- and right-click buttons and a scroll wheel (which has tactile, click-to-click scrolling). The dpi is listed as 1200 by Genius. Operating proved to be exceptionally smooth with zero lagging found, even in the extra-smooth spot on my wood desk that has proved to be problematic for other mice. I did not need a mouse pad.
Setup was plug-and-play and immediate: Just insert the pico receiver into an empty USB port and wait a few minutes for the computer to recognize the device. No need to download any drivers.
Design
The mouse also has an on/off switch, an especially important detail for travelers, because who wants to hunt down batteries while you're on the go?
The Traveler 6000 is an ambidextrous mouse -- left-handed users rejoice! -- but this also means that there are few ergonomic curves to it. Despite this, it was found to be comfortable during long-term use over a period of a little more than a week.
I tested the Black Diamond version of the mouse; it also comes in Royal Blue and Ruby Rose.
