IST PLUS
Description:
IST PLUS is the next evolution of ELECOM’s IST trackball line, born directly from customer feedback. It builds on the ergonomic foundation and smooth ball-roller feel that made the original IST popular since its 2023 launch, while upgrading connectivity, onboard memory, and switch quality.
IST PLUS features dual wireless connectivity (Bluetooth LE + USB 2.4GHz), multi-device switching across up to three devices, onboard memory with three saveable profiles, and silent switches on all buttons. It retains the IST’s signature 36mm thumb-operated ball with the patented debris-resistant ball-roller support structure.
