Kensington's thumb-operated vertical trackball, the Pro Fit Ergo TB675 Vertical, arrives in Japan on June 30 in its wireless model. Its 60-degree vertical design eases the strain of your grip, while three connection methods — 2.4GHz, Bluetooth, and wired USB-C — let you switch among up to four devices. The Amazon-exclusive model is priced at 11,520 yen, and preorders have already opened. It is a strong option for anyone who finds flat mice tiring or who works across several computers.
A Wrist-Friendly 60-Degree Vertical Design
The Pro Fit Ergo TB675 Vertical is a trackball built around a body tilted at 60 degrees. Because you hold your palm upright, it reduces the forearm twist that often comes from gripping a flat mouse for long stretches. The contoured body is shaped for average-sized hands, and you move the cursor by rolling the large ball with your thumb.
The ball measures 34mm across and is paired with an optical sensor. Tracking resolution switches across four steps — 400, 800, 1,200, and 1,600 dpi — covering everything from detailed work to sweeping across a wide screen. The body measures 98 x 130 x 67mm and weighs about 180g. The ball pops out with a dedicated button, so you can quickly clear away the dust and grime that collect underneath. In design lineage, it follows the 2021 Pro Fit Ergo Vertical and the 2023 Pro Fit Ergo TB550.
Switching Among Up to 4 Devices over 2.4GHz, Bluetooth, and Wired
It supports three connection methods. A 2.4GHz wireless receiver with 128-bit AES encryption handles one device, Bluetooth covers two, and wired USB-C adds one more, for up to four devices connected at once. You switch with a button on the underside, so you can move between a work laptop, a home desktop, and a tablet at the press of a single button.
The wireless model charges over USB-C. It offers a long runtime of up to four months on a single charge, and you can keep using it while it charges. An LED indicator on the side shows the remaining battery, reducing the chance of being caught off guard by a dead battery while you are out.
A 4D Scroll Wheel, Nine Buttons, and Konnect Customization
The controls are well thought out. The scroll wheel is a metal 4D type that adds side-to-side scrolling when tilted, on top of the usual up-and-down scroll. It is handy for wide spreadsheets and timelines.
There are nine buttons in total: left and right click, a middle click, forward and back, two programmable side buttons, and a dpi switch. The dedicated Kensington Konnect software runs on macOS and Windows, letting you assign functions to each button and set up macros in one place. It offers the kind of customization you expect from a desktop input device rather than a compact folding mouse. It comes with a three-year limited warranty.
Price, Release Date, and Elecom's New Trackball
The model sold in Japan is the wireless K72171WW, handled from June 30 by ACCO Brands Japan, which carries Kensington products. The Amazon-exclusive K72171WW is set at 11,520 yen, lower than the retail-store model, with preorders starting alongside the announcement.
Choices in vertical trackballs look set to grow this summer. Elecom has also announced the IST PLUS, the latest model in its IST series — a thumb-operated wireless trackball that uses a ball-roller support unit rotating freely in all directions, together with a high-performance bearing support unit from Minebea Mitsumi. Priced at 8,380 yen and 10,980 yen, it is set to go on general sale in late June. For those looking to ease the strain on their wrists, the field of options worth comparing is filling out.
Summary
The Pro Fit Ergo TB675 Vertical is a wireless trackball that eases grip strain with a 60-degree vertical design and a thumb-operated ball, while letting you switch among up to four devices over 2.4GHz, Bluetooth, and wired connections. Practical features round it out, including up to four months of battery life, a metal 4D scroll wheel, nine buttons, and Konnect customization. The Amazon-exclusive model costs 11,520 yen, with release set for June 30. For anyone growing tired of flat mice, it looks like a device well worth considering as a switch.
