If you have to push the button twice to get it to work. I believe this is a result of the battery issue that is well documented in this forum. The first button press wakes the remote up and the second button press actually fires off the IR signal. This has been known to occur in as little as 24 hours after replacing the batteries. The remote batteries will drain completely not long after this starts happening. On average with my LEDs at 0% I'm getting anywhere from a few days to a couple of weeks before the batteries are completely drained. Also, after testing the batteries, it seems that one drains faster than the other, but it still causes the remote to stop working.
