After we purchased this laptop in February, about 3 months later we started having issues.  We took it to an Apple store and had it scanned.  The rep at the Apple store told us that it was checked by them back in December by the former owner and told it needed a $600 repair.  The former owner declined the needed repair and just had the laptop restored to factory settings, which temporarily made the device function okay.  Then they sold it to us knowing full well that it needed a $600 repair, which they hid from us.  We have the print out from the Apple store with all of this info on it. The company finally agreed to give us our money back, but we have been without a laptop for over a month going back and forth with them.  Not a trustworthy company.
