CST-TrackBall

The Scent of “Made in the USA”	Combining with Foreign Keys	For use with the left hand

　Kensinton While the company’s trackball often comes up in conversation,CST rarely does. The reason I love this trackball is that it’s Made in USA, and since the ball itself is 57 mm in diameter, you can swap it out for a billiard ball. For a while, you could do this with the Kensinton model as well, but it’s no longer possible—likely because it switched to an optical sensor, which requires a special surface treatment.

　I own several devices that I love, and I have two of this one, too. Oh, right—CST went bankrupt, and its operations were transferred to us. ↗ If you’re interested in a large trackball, I hope you’ll buy one. You can enjoy the classic “squeak” of the bearings.

　Well, this one’s just taking up space, so it’s out of service for now…
