Sometimes it’s better to let the advertisers speak for themselves:
“A clicking sound of mouse would bother you when using PC in the midnight at quiet place, especially like where somebody is sleeping nearby.
“As for conventional mouse, the sound comes out by metal switch, while our Silent Mouse 2 uses Silicone instead. It is silent because the click button only pushes silicon to react as the mouse click. Since not only a click part but also a wheel part uses silicon, all the movement of a mouse has the structure of noise prevention. In addition, various measures are taken to prevent noise, such as button shape design to prevent resonance.
“Also we have fine tuned to improve feel of use including click feeling etc.”
’nuff said. Cute though.
