My old Mid range harmony remote
Has worked perfectly for 7+ years except for the 6 button which was broke when I got it and I never bothered to exchange it.
During that time its worked perfectly and can transmit faster than my newest AV equipment can react.
The website which was a little clunky at times has been much faster in the last few years.
About the only complaint I have is that the newer mid range remotes are limited to too few pieces of equipment compared to my old model.
