Overview

The Buffalo BSMOU27SMRD is a wired mouse built around quiet clicks. Its red shell carries just three buttons, and the body is sized as an M-size shape that sits naturally in the hand. Because it connects over USB Type-A, there is no pairing step and no software to install before it works.
This is a mouse for people who share a room or work late. The optical sensor removes the maintenance that comes with older mechanical designs, and the wired connection means no battery to swap or recharge mid-task. It is a straightforward input device rather than a feature showcase.
Pricing places it firmly in the entry tier, which makes it an easy addition as a spare or as the mouse for a secondary machine. Nothing about it is flashy, but the basics of daily pointing and clicking are covered.

Connectivity & Compatibility

Connection is wired, and the mouse is listed as compatible with devices that have a USB Type-A port. That covers desktop and laptop computers, and the manufacturer also lists tablets and game consoles among supported hardware. With no pairing or charging involved, moving it between machines is simply a matter of unplugging and replugging.
The listed dimensions are roughly 58 mm long, 100 mm wide and 40 mm tall, with a weight of about 100 g. As an M-size model, it should suit a wide range of hand sizes rather than only small or only large grips.
The three-button layout keeps left click, right click and the scroll wheel as the whole control set. Anyone who does not rely on macro keys or side buttons will find the arrangement immediately familiar.

Product Info

The model dates back to April 2015 and has stayed in the lineup since, which says something about steady demand for a simple wired mouse. At a price in the low hundreds of yen, it sits at the entry end of the market and is easy to justify as a first mouse or a stopgap replacement.
Its position is clearly entry class. Buffalo trimmed the feature list down to quiet operation and the convenience of a cable, leaving out high-resolution sensors and extra buttons to keep the cost down. That makes it a poor fit for buyers chasing precision or customization, and a sensible one for buyers who mainly want a quiet click and dependable basics.

Best Use Cases

  • People working late at home: the reduced click noise keeps typing and browsing from carrying through a quiet house, though anyone who prefers a crisp, loud click will find it soft.
  • Anyone who wants a spare on hand: the wired design removes battery and charging worries, and the low price makes a drawer backup easy, while wireless-only setups will not suit it.
  • Office and document work: three buttons cover everyday tasks without a learning curve, and the optical sensor needs no cleaning, but gamers who map many commands will run out of buttons.
