Sweex is best known as a manufacturer of computer peripherals. Its portfolio also includes a number of other products such as MP3 players, chargers, digital frames, etc.

The MI511 is an affordable optical mouse from Sweex for everyday everyday use with a flattering design. The optical sensor is more accurate and many times more sensitive than conventional ball mice. Compared to them, it has a number of advantages: it does not need to be cleaned - the LED diode, hidden in the mouse chassis, does not come into contact with the pad and does not clog. An optical mouse is also able to work on virtually any, usually uneven surface. The resolution of the sensor used in the Sweex mouse reaches 1200dpi, making the mouse ideal for versatile use.

A mouse of modern design, it offers two buttons inconspicuously recessed into the body and a scroll wheel that, among other things, can act as a third button.
