Kensington is giving its iconic trackball mouse a serious overhaul. The company has unveiled the Expert Trackball Mouse TB800, a modernized version of the long-standing Expert Mouse K72359WW that’s been a staple in editing studios and control rooms for years. The new TB800 keeps the distinctive look and feel of the original but adds a sleeker design, more buttons, and an expanded range of controls aimed at power users and creative professionals.
Set to launch in November or December for $150, the TB800 introduces several upgrades that make it more versatile than its predecessor. Kensington has slimmed down the body, giving it a profile closer to the company’s SlimBlade model, while keeping the signature central trackball and ring-style scroll dial. The familiar four-button setup remains, handling left and right clicks up top and page navigation below, but the new version adds an entire row of customizable media buttons along the top.
Perhaps the biggest physical change is the addition of two side-mounted scroll wheels, allowing for horizontal scrolling or zoom adjustments without relying on key combinations. Beneath the mouse, hardware switches let users disable individual scroll wheels, tweak DPI sensitivity, and toggle between smooth or stepped scrolling modes.
In terms of power, the TB800 moves away from AA batteries in favor of a rechargeable USB-C battery system. While that’s more convenient for charging, it does cut the battery life from the old model’s near-year runtime to about four months per charge. Wireless options include Bluetooth and a 2.4GHz USB receiver, though it can also operate as a wired device for users who prefer zero latency.
The TB800’s refinements make it clear that Kensington isn’t chasing minimalist mouse trends but rather doubling down on precision and workflow flexibility. The customizable buttons, multiple scroll inputs, and high-accuracy ball remain ideal for tasks like video editing, audio mixing, and design work where fine control is key.
The original Expert Mouse has long been a cult favorite among trackball loyalists thanks to its ergonomics and gesture potential. With the TB800, Kensington seems intent on keeping that legacy alive while giving professionals the modern connectivity and customization features they’ve been asking for.
