Dropping PRS 300
I dropped my PRS 300 from about 5 feet. It was in the cover that comes with it and it slipped out of my hands onto a concrete floor.
There was a very minor smude/scratch on the corner it fell on. The reader automatically reset due to the hard impact.
i lost about 50 books because it reset to the setting prior to my last down load.
I also dropped it from about 5 feet, out of the case onto a linolium floor. No damage and no reset.
Have had absolutely NO problems with it at all. So, I'd say it is pretty sturdy.
