I deliberately waited until after a month to write a review because this has given me ample time to use the computer and detect issues.  So far I am very pleased with this computer, I have experienced none/ zero issues. It came packaged carefully and in immaculate condition. If I do not tell people that it is used they would not know because it appears new.  I did not have to call Technical Support because I figured it out myself. The only reason why I am not giving a 5 star rating is the raggedy Macally keyboard and mouse that came with it. They were useless; the iMac did not recognize them at all. It was a good thing that I had the presence of mind to purchase a keyboard and mouse combo before the iMac arrived. The combo I bought worked perfectly/like charm. Otherwise, I am pleased with this iMac purchase and loving it.
