Clearly superior technologies CST1350SA trackball mouse

This Kid-Trac series of three button trackball has the precision-ground ball and mirror-finished rollers deliver a smooth feel and effortless control. The design is completely ambidextrous, accommodating either right or left-handed users. The extra large ball and contoured profile allow for easier control and accommodates hands of all sizes from children to adults. Hardwired into the trackball is its unique ability to dynamically accelerate across the screen in response to the speed with which you move the trackball. Excellent gift for someone who already has everything, and everything he has is always bigger than anyone else's... Kinda like BMW for some people.

Features:

• Middle button hardwired for drag-lock:
  • The middle button is a drag-lock - this means that there is no need to hold a button down to highlight, select or drag an item. This is a real plus for individuals with trigger finger, who are constantly having to click, or for those with motor skill difficulties.
• Middle button in scroll-lock mode:
  • The middle button can also act as a scroll-lock. To have the button perform a scroll-lock (instead of the default drag-lock), press and hold the button for 2,5 seconds and it goes into scroll-lock mode. To leave scroll-lock mode, press any button again.
• Universal compatibility:
  • The universal compatibility of this design means it works well in a multi-user environments.
• Low profile:
  • Trackball's low profile case acts as a natural hand-rest, mirroring the natural contours of the hand.
• Switch adapted model:
  • This switch adapted mode trackball is a three button device that has three 3,5 mm audio jacks positioned on the left side of the trackball. These jacks are arranged in parallel to the buttons on the trackball, and you can plug in any standard switch to generate the 3 different button actions corresponding to the regular buttons (left click, drag lock, right click).

Ergonomic Benefits:

• Reduces arm and elbow movement.
• Like a touchpad, the Kid-Trac trackball is a stationary pointing device. To move the cursor on your computer screen, you simply move the ball with your fingers (the ball itself is anchored in the trackball housing). Because of this, you can greatly reduce arm and elbow movement, relieving stress both to the arm and shoulders.
• Uses less space than conventional mice.
• The stationary nature of the Kid-Trac trackball also allows you to conserve space on your workspace. It is ideally suited for space restrictive environments or narrower keyboard trays that can accommodate a keyboard with only a few inches extra to spare.
• Hard-wired drag lock feature reduces finger fatigue.
• The hard-wired drag-lock feature allows you to activate drag-lock by simply clicking on the middle button without having to hold down the button while you drag the selected item on the computer screen. This will simplify using applications that require significant click-and-drag actions. There is also a scroll-lock feature that allows you to horizontally and vertically scroll without having to hold down a button. By not having to continually hold down the button while dragging with the mouse, finger fatigue can be greatly reduced.
