This unit - which I watched for a while - was on sale in Amazon occasion.
It was stated to be "in good condition" and also that the device would repacked in plain packaging.
Usually I Nachete not used but the price reduction was interesting.
I had a little apprehension but in fact the unit I received is new.
I examined it from every angle, no scratches, no marks, the stickers were new, perfect screen even in oblique light, even the accessories are new (manual, headphones, battery).
In short, the only difference with a new unit is just at the outer packaging which is neutral instead of packing the Olympus brand.
And of all this for me ...
All that to say that you can trust to Amazon occasions.
Furthermore you no risk because you have 30 days to return the product.
