I used before buying this corded keyboard a wireless keyboard and a wireless mouse (names I will not name) the daily cost me a lot of nerves because this system was not working properly and while writing mails or other documents there were dropouts of letters repeatedly. Since I use the beautiful white keyboard and mouse I can finally write without having to constantly readjust. Keyboard and mouse are working properly, the letters are clear to read, and the keyboard looks very classy one at that on my desk !! I would recommend this product only!
