Microsoft Wireless Optical Desktop Pro (K48-00001) Keyboard and Mouse

I purchase the Microsoft Desktop Pro Keyboard and Mouse after I was getting sick and tired of replacing mice because the cords stop connecting properly from use. I love the fact that it is all wireless because there really is nothing I have found that can break on it. I use it for hours a day and my twelve year old daughter probably abuses it but it has stood the test of time. I have had it for two years now and have never had a single problem with it. I was hesitant to purchase it because I was not sure of the battery life but the original batteries I had installed in it lasted me for about a year. I really could not ask for more than that especially that it is used so often. I have since replace the unit with rechargeable batteries and have not even had to recharge them yet. It is really easy to set everything up. The keyboard is ergonomic and very comfortable to use and using the tangle free mouse is an absolute pleasure. There are many cool buttons on the keyboard including calendar, mail and my document buttons along with many useful keys to store information for the internet. I am so happy with this purchase and have recommended it to friend who have made the same purchase and have absolutely no complaints.
