IOGEAR's new 5-Button USB Laser Mouse (the vanguard product in the company's new Laser 1600 Series) is an excellent tool for graphic designers, gamers, and desktop users. This new IOGEAR mouse uses VCSEL (Vertical Cavity Surface Emitting Laser) as the light source, which provides 30x more tracking power than regular mice using an optical sensor. This means that the USB Laser Mouse will work on virtually any surface, with its extremely high resolution of 1600 dpi. Take full control of your computer with IOGEAR's 5-Button Laser Mouse. Two conveniently located side-buttons allow you to easily go back and forward in your web browser. Furthermore, the Instant-Access button, located right below the scroll wheel, quickly launches Microsoft Word, Excel, PowerPoint, Outlook, and other programs with a simple mouse click. Within Microsoft Office applications, the instant-access button allows you to perform common tasks such as Open, Save, Copy, Paste, and Print.
