Actually, I think it went through two washes... and still works perfectly I run three times a week and clip it to the pocket of my shorts so it was only a matter of time before it happened. Seems to have gone in once then remained in the machine and gone around again before I noticed it there. Cosmetically it barely has a mark on it. A few minor scuffs on the top and bottom edges but that's it. Maybe I'll drive over it with my car for the next 'test'.
