These guys do not know what they sell. This was a marketing ploy, I did catch him once before and made him change his listing. All a sudden he had used and new. Checked with him, claimed he ha d gotten some new ones bought one, looked very used took the back off, strong discoloration a give away but frequency way down a sign off long operating time, because FE ships them as close as possible and claim 5 E-11. Those of you that paid the extra for a NEW got ripped off. Bert Kehren In a message dated 2/21/2012 1:37:59 P.M. Eastern Standard Time, albertson.ch...@gmail.com writes:

If you have many FE5680s, yu test them and sell the good ones first as you repair the failed units. On another list people were asking if they should buy a "reconditioned" product from Apple. (Apple offers the same 1 year warranty.) The majority opinion is that the "reconditioned" units have a better record because they were bench checked here is the USA and have better quality assurance testing than the new units get in China. This may be true of the re-worked FE5680s too. A reworked unit might have been tested for 30 minutes or so while the others only got powered up briefly. We don't really know the level of testing but over all these seem to be reputable sellers who are responsive to problems. I do avoid sellers who claim their stuff is "new" when it can't be new. Either their understanding of the English word "new" is poor or they are misrepresenting the product. Either way there are others who don't misuse the word that I can buy from.
