Bests & Worsts Reviews from Amazon

I have loved this keyboard. When the space bar, 7 key, ; and other keys ceased to function and is still in warranty, Logitech has me talk to multiple technicians, all of whom keep asking me to do the same tasks over again. I have talked with over 3 techs now and they have not read what I have done with the other technicians. It has been over 10 days now of waiting to get approval for warranty replacement (it supposedly has a 3 yr limited hardware warranty) and it does not seem to be coming anymore. They no longer respond to my emails. I have purchased many Logitech items over the years and thought they were a good company, but seeing this lack of honoring their warranty has made me rethink their products and customer service. I will now be referring most of my friends and coworkers elsewhere.
