Took the Touches out of the box, set them up the other night, they worked great. Come back to the same desk a few days later, nothing has happened to them, haven't changed my setup, and all of a sudden the left Touch is out of commission. White LED light won't turn on, etc. The right one is fine. I swapped out the battery, tried removing and re-pairing, etc. Nothing. Very disappointing.
UPDATE: It turned on after I held down all the buttons at once on it. I dunno, man!
