I just spent approx 10 minutes on the phone to Logitech technical support to log a ticket for my dead Harmony 1100i.
About 3 weeks ago it started to give me problems, and about a week ago just died. Most disappointing and frustrating. I’m amazed how annoying it is to have to go back to multiple remotes. Fortunately I had access to my old 525, and reprogrammed it to get by.
As far as logging a warranty claim, it was one of the best service desk experiences I’ve had. The consultant was polite, knowledgeable, listened to what I said, didn’t ask me to do steps I’d already done. After a short period he had efficiently arranged an exchange reference for me at my place of purchase. It was simply one of the best warranty claims I’ve ever had to make.
