5 Review for Microsoft Wireless Desktop 800 Keyboard and Mouseibbi1234 | 12/01/2011 | See all ibbi1234's reviews (1)Recently bought this and what can i say, it is awesome. Not only is it very stylish but the range is great. Normally wireless keyboards and mouse have maximum of 2metres range but i tried this at 5metres and it worked without and lag. Batteries seeming to last a long time, I am a gamer and normally play around 10 hours a day and the batteries for both of these are nowhere near depleted after all this time.Also has a few useful extra buttons such as volume control and calculator and also very quick and easy to install. Once you plug it in it works. Great product and also very cheap compared to normal wired keyboard and mice.
