Overview

The Buffalo BSMOU27SMBL is a wired three-button mouse that connects through a standard USB Type-A port. Its defining trait is a silent click design that keeps the usual clatter out of shared rooms, open offices and late-night desks. It sits in the M-size class, a middle ground meant to suit a wide range of hand sizes rather than one narrow audience.
The shell follows an ergonomic shape aimed at a natural grip, so longer work sessions should feel less tiring on the hand. Tracking comes from an optical sensor, which means no ball to clean and no periodic maintenance routine. The blue finish also gives you something other than another black rectangle on the desk.
Because it is wired, there is no battery to replace and no pairing step to repeat. It is the straightforward choice when reliability matters more than cable-free convenience.

Connectivity & Compatibility

Connection is wired, and the supported devices are anything with a USB Type-A port. Buffalo lists PCs, tablets and game consoles, so the mouse is not tied to one platform as long as a free USB port exists.
There is no separate receiver or Bluetooth link involved, which removes interference and re-pairing from the list of things that can go wrong. Plug it in and the mouse is expected to be recognized without extra setup.
The catch is on the host side: a laptop with only USB Type-C ports will need an adapter. Cable length and button reassignment are not covered in the available information, so check your own desk layout before buying.

Product Info

This model was released on April 14, 2015, and carries the part number BSMOU27SMBL. Its listed dimensions are roughly 58 mm long, 100 mm wide and 40 mm tall, with a weight of about 100 g, which fits the M-size positioning.
In the market it reads as an entry-level practical mouse. Buffalo kept the essentials, a quiet click and an optical sensor, and left out multi-button layouts and high-resolution sensors. That keeps it an easy add-on for office work or as a spare.

Best Use Cases

  • People working in quiet spaces: the muted click suits night-time home work or shared rooms, though anyone wanting extra side buttons will find it limited.
  • Users who dislike charging routines: power comes over the cable, so battery level never enters the picture, while cable-averse desks should look elsewhere.
  • Anyone keeping a backup mouse on hand: a USB Type-A port on a console or tablet makes it a flexible stand-in, but it is not aimed at precision gaming.
