Kensington SlimBlade Pro Wireless Trackball - Precise Desk-Saving

In this review the Kensington SlimBlade Pro Wireless Trackball is assessed as a precision-focused, desk-saving input device for users who value comfort and accurate cursor control. The SlimBlade Pro stands out because it combines a large 55mm finger-operated ball with multiple connection modes, giving users the option of Bluetooth, 2.4GHz wireless dongle or a wired USB-C connection. For those who frequently switch devices or need a compact footprint to free desk space, this trackball offers the clearest single reason to buy: high-precision tracking with flexible connectivity in a low-profile, ambidextrous package.

Key Features

• Three connection modes: Bluetooth, 2.4GHz wireless and wired USB-C provide flexible pairing so users can move between laptops and desktops without hassle.
• Large 55mm ball with dual sensors: Dual sensors deliver more accurate and responsive cursor control, which reduces wrist and arm movement during detailed work.
• Rechargeable battery: Built-in battery charges over USB-C and delivers long run time so the device stays usable for months between charges.
• Low-profile, ambidextrous shape: The shallow design conserves desk space and accommodates both right- and left-handed users for comfortable all-day use.
• Programmable buttons via software: Free KensingtonWorks software lets power users assign functions and customize up to eight button sets for a personalized workflow.

Who It's For

The SlimBlade Pro is best for professionals and power users who need precise cursor control for tasks like photo editing, CAD work or detailed spreadsheet navigation, and who appreciate a smaller desk footprint. Its rechargeable battery and multiple connection options also suit people who switch between a laptop and a desktop or who travel with a single peripheral.

It is less well suited to users who prefer thumb-operated trackballs or those who expect an identical feel to a traditional mouse; several users note a brief learning curve. If you need a simple plug-and-play mouse with minimal adaptation time, a conventional wireless mouse may be a better fit.

Pros & Cons

Pros

• High-quality build and smooth 55mm ball give confident, precise tracking for detailed tasks.

• Low-profile design saves desk space and supports comfortable use for both hands.
• Programmable buttons and downloadable software allow meaningful customization for power users.

Cons

• Some users report a short learning curve and mixed feelings on scrolling speed and button feel, so immediate comfort is not guaranteed.
