I purchased this new from a mass retailer about three years ago. I used it for backing up photos. My usage was mostly in hibernation, with the device resting for the majority of the day, except for when backing up photos and occasionally viewing them. It works without any problems. I am a non-smoker, and I do not have any pets. I will include a printed copy of the manual, which I downloaded from the web. It has been lightly cleaned. The HDD is not included, so please prepare your own. Thank you.
