Kensington ProFit Ergo TB450 trackball, langaton

The Pro Fit® Ergo TB450 Trackball combines the feel of a wireless mouse with the precision of a trackball. Its sculpted, 45° tilted ergonomic design improves wrist and forearm alignment, takes up less desk space than a conventional mouse and is intended for comfortable extended use. The device offers dual wireless connectivity (Bluetooth® Low Energy and 2.4GHz with included nano receiver), long battery life, a patented ball ejection system for easy cleaning, high-quality optical tracking with four DPI settings, and is manufactured using 50% recycled plastic to reduce environmental impact.

Advantages

The 45° tilt supports a more natural hand position to help reduce strain during prolonged use. Dual wireless connection options provide flexibility to connect to multiple devices or environments. The patented cleaning system allows fast removal of the 34 mm thumb-operated trackball for maintenance. Long battery life and Plug & Play setup simplify operation, while 128-bit AES encryption secures wireless communication. Made partly from recycled ABS, the TB450 reduces plastic usage without compromising build quality.
