I no longer need this amazing remote. It can control all your electronics and is programmed from the web. Once it is set up....the remote replaces every remote you have and controls every device in your home theatre set up. It can also learn any IR remote. The lithium battery ran out on us and I replaced it last December (should last 4 years). I bought another lithium battery as a back up and I will include that as well. Comes with adapter cable for computer, charging base and wall wart. instructions are available online at the Logitech site. Used...these go for $40-80.
