The real problem is the hard coded key time-out value. I suspect every 15C LE will once in a while (every couple of hundred keypresses or so) show double registered entries. They appear real fast, so that a slightly higher value would have eliminated this problem.

The new 12C also has this problem. I had one that would double register a bit more frequently than every 100+ presses. Had to sell it. That however, brings a new question to the table: If the firmware was not meaningfully modified, could this problem be related to some hardware incompatibility? The bugs in the 15C LE, being related to the UI mostly, supports this theory.
