PROMATE SamoTri White Tri-Connect Wireless Mouse / Dual Bluetooth 5.0 / 2.4GHz Connectivity / Multi-Device Switching (Up to 3 Devices) / Smart Flying Adaptive Scroll Wheel / Adjustable DPI Up to 3200 / Rechargeable 500mAh Battery / Up to 100H Usage / USB-C Fast Charging / Ergonomic Design / SAMOTRI.WHITE / SAMOTRI.WHITE

The Promate SamoTri in white is a tri-connect wireless mouse with two Bluetooth 5.0 channels and a 2.4GHz link, switching across up to three devices. Its sensor adjusts to 3200 DPI, the smart flying adaptive scroll wheel handles long documents, and a rechargeable 500mAh battery runs for up to 100 hours between charges.

Three separate wireless paths are built in: a pair of independent Bluetooth 5.0 connections and a 2.4GHz link. Bluetooth suits thin laptops and tablets with no port to spare, while 2.4GHz gives a desktop the lower-latency option, so the SamoTri adapts to whichever machine is in front of you.

Multi-device switching handles up to three computers, so a work laptop, a home desktop and a tablet all answer to the same mouse without repeated pairing. For desks running two systems side by side, that removes the second mouse and the constant reach past it.

The smart flying adaptive scroll wheel responds to how hard it is spun, so a small nudge steps line by line while a flick sends it spinning through a whole document. In long spreadsheets and web pages that difference removes dozens of separate scroll movements from an ordinary working day.

Tracking sensitivity is adjustable up to 3200 DPI. Low settings suit precise selection in design tools and spreadsheets; the upper end covers large or high-resolution monitors, where a low-DPI mouse takes several sweeps of the mat to cross the screen once.

The rechargeable 500mAh battery is rated for up to 100 hours of use, which under normal working patterns means charging in weeks rather than days. A built-in cell also removes the recurring cost and the drawer of spent AA batteries that disposable-cell mice leave behind.

The SamoTri charges over USB-C with fast charging, so it shares a cable with current phones, laptops and other peripherals instead of needing something specific. On a mouse the practical benefit is that a brief top-up during a break is enough to finish the working day.

This version wears a white finish over the same ergonomic body, contoured for the hand rather than shaped as a flat slab. White suits desks built around light monitors and pale surfaces, and the ergonomic profile is what decides whether a mouse is still comfortable four hours into a session.
