Every Logitech device I've ever owned has broken within a year. This one never worked right. Every device had maddening setup and software. This one is no different. I am on a mac, it is horrible. Took 10 installations, countless hours in forums, downloading and reconfiguring java just to get the software right. Then it is the most archaic interface on a product today, once installed, the activity button doesnt work. If you press POWER, it brings you to activity. Woops. Most important button to the remote doesnt work. My last one broke in a year, no replacement. Before that, the battery didnt fit right so I had to jerry rig with plastic to get it to charge. It would constantly register in the charge and beep at us all night. My wireless keyboard from them never held a full charge. No replacement. Dropped the bluetooth connection constantly. I get better functionality from a $5 app on my iphone.
