My worst was falling asleep and having it take a tumble from my hand down to the carpet. It hit the bed frame in the bottom right corner hard enough to have a little silver scratch (where the gunmetal gray/black got scratched) that really only I notice. Reader's just fine.
Yesterday mine fell off the couch arm to carpet when my pillow whacked it. It bumped against the wall (and caused me to let a cuss word fly)

but it's still no worse for the wear.
