I have been happily using Logitech keyboards and mice for a long time. BUT-- my most recent purchase, an MK710 Keyboard, has given me a reason to review those choices. The Lettering on 9 to 10 keys has warn off ALREADY. What is it cheep paint lettering or what? I don't use my keyboard as often as my secretary and her keyboard is 10 Times as old as mine and she STILL has all of her lettering on her keys. For what we pay-- you should be doing a better job.
