I experienced a near heart attack the other day. I had my R4 in my pocket (inside the little blue carry case) and somehow it managed to slip out while getting into my car (unbeknown to me). Well, It was run over as I backed up. I saw the poor thing lying there as I got further back and nearly crapped myself. Well, After inspection, the blue case as been cracked and will no longer latch closed however, the blue rubber padding was not harmed and the all important R4 inside was completely intact. Gotta love great engineering.
