I bought the 880 from Best Buy a month ago, and it worked fine, but would not charge all the time, as the previous member stated. The contacts barely touch, and the result has been a dead remote on more than one occasion. Sad, for a $250 remote that becomes a massive paper weight when dead.
I emailed Logitech's tech support, and never got a reply. I did get an autoreply that said since I hadn't contacted them in 48 hours since my initial email, that the problem must have been resolved.
So, I called them on the phone, and sat on hold for...no lie...35 minutes...until someone answered. He took my info and told me the RMA people would be in contact with me within 48 hours.
My review...nice remote, not quite all it's hyped to be. Buttons are smallish, especially around the LCD screen. The programming interface on the PC is ok, but could be better, perhaps say graphical rather than question based. The remote also feels cheap. It feels like it's going to break, at least IMO. But, it does control everything I need it to, so functionally, when it's charged, I like it.
