Techradar posted a review on the Microsoft Wireless Optical Desktop 700

Obscure Washington outfit Microsoft present us with this, the Wireless Optical Desktop 700. It's been fairly inconsistent in the design and quality of its peripherals lately, swinging from the sleek Arc Touch to the almost unusable Windows 7 Touch mouse. Recommended at £30 but available for a shade over £20, the Wireless Optical Desktop 700 features a well-built keyboard running on AAA batteries and a slightly flimsy mouse running on AAs, each communicating with your PC or laptop via a wireless receiver. Key feature As far as this reviewer's weary fingers are concerned, the best thing about this package is the weighting of the keys.
