What we love- SilentTouch technology keeps your clicks super-quiet, so you won't disturb anyone while you're working- The SmartWheel offers two speeds, so you can switch to fast mode and scroll down long pages in no time- 2 programmable side buttons let you save favourite shortcuts and work faster, with fewer clicksGood to know- The mouse connects wirelessly over Bluetooth or with the USB receiver, so you can use it with almost any device- 2 years of battery life mean you won't have to worry about running out of power- The rubber side grips and contoured design make it comfortable to hold, whether you're left- or right-handed
