I received a unit that had a non functioning headphone and microphone jack. Other than that the computer functioned flawlessly and was exactly as advertised. But I have a special needs child that needs the headphone and microphone jack to use several educational programs. I was sent a replacement machine without any hesitation. I have not set up the replacement yet but I appreciate how quickly and easily it was replaced. However it is still a pain to set up a machine then have to take it all down, repack it and ship back only to have do the work all over again. Maybe a little more testing is needed before a machine goes out the door as "refurbished".
