"This pre-owned product has been professionally inspected, tested and cleaned by Amazon qualified vendors.- This product is in "Excellent condition". The screen and body show no signs of cosmetic damage visible from 12 inches away.- Accessories may not be original, but will be compatible and fully functional. Product may come in generic box."OK, so this thing was NEVER CLEANED and begs the question of what passes for an Amazon-qualified vendor.  The picture of the top cover with the red circle is my 30-second clean-up with some rubbing alcohol.  I had already blown out the dust under the cover before I took this picture, and I'll still need some time to clean up those 2 USB ports.2-stars for value because the computer boots up, but the included DELL keyboard was DOA (no lights, wouldn't connect to other computers); the upper, clean & dark keyboard is mine for contrast.  The DISGUSTING mouse may work (lights up with a battery) but it will not talk to the included BT adapter & is likely mismatched hardware.  WiFi seems to work fine.  But I will spend an hour cleaning this thing & I still need to order another mouse & keyboard.1-star is generous for this review.  It would have been better off not shipping with a keyboard & mouse.  Instead, it's a mess of UNCLEANED hardware that probably just gave me the plague.
