The Kensington Expert is the trackball that I have used for many years. Yes, it’s one of my favorites, so expect nothing but praise! This is a winner, especially for professional users.
The Kensington Expert Mouse, one of my favorite trackballs, is now available as a wireless model, the first Bluetooth trackball! It also features a USB dongle if you don’t have Bluetooth.
The Kensington SlimBlade could very well be called the Ferrari of the trackballs. Expensive, it looks utterly amazing and is full of cutting edge technology. I used to use it as my daily driver for many years, and I love it, but it takes a daredevil to actually buy this as your first trackball.
The CST2545 is a high quality trackball, made in the USA by Clearly Superior Technologies. There are several CST2545 variations available, I’m testing the top of the range model, the CST2545-5W (GL) L-Trac Glow Laser Trackball with blue glow trackball (how cool is that!).
