I am also having very good results so far. However, every now and then a button press does fail but I have, so far, been unable to determine if it's the remote or the cable box. Everytime it fails I'm not looking at the remote but at the TV. Then I start watching the remote very closely but, of course, it doesn't fail when I'm watching the remote. It knows I'm watching it and doesn't want to get in trouble so it behaves when I'm paying attention to it ;=).

I will attempt to "catch it in the act" over the next couple of days so I can pinpoint if it's the remote or the cable box. I'm not using RF so I know that's not the problem.
