We've been using the Apple Remote as our remote for our LDR preamp products for well over a year now. We commission new preamps with new Apple remotes every week and have found the Apple remote to be very reliable.
Recently one of our customers purchased their own Apple remote and proceeded to pair it up with their preamp but were not able to get the pairing to work. Of course I then tested things here and went back and forth with several Apple remotes with no trouble. Hmmmm.
Then today as I was commissioning a new preamp with a new remote the preamp was balking at certain commands and generally being flakey. I then paired the preamp up with a different remote and everything worked as normal.
I'm now convinced that every so often Apple builds a lemon remote that kind of works but not quite right. If you run into this problem with a remote you purchased from us please let me know. If you purchased a remote somewhere else I suggest you try to have them replace it.
Again, the Apple remotes are usually flawless but once in a while you'll find a rotten Apple...as it were.
