I purchased a Microsoft Wired PS/2 Keyboard from Amazon.com one month ago, to replace two previous keyboards (another brand) which were unsatisfactory due to fading or chipping of the letters from the most frequently used keys. I presumed that a "name brand" (Microsoft) keyboard would be of superior quality, giving me longer service. I was wrong. My previous "generic brand" keyboards lasted 6 to 8 months each, before certain frequently used letters disappeared from the keys. My Microsoft PS/2 keyboard had been in service just one month, and 5 or 6 frequently used letters are already faded to the extent that they are likely to disappear completely in another month. I am extremely disappointed in the quality of the Microsoft keyboard I recently purchased from Amazon.com.
