A little over 6 months of using it and it crashed.  Unable to boot to Windows and unable to recover from backup.  I had to reinstall Windows 10 from a copy that I already owned.  I back my computer files up every Sunday so I didn't have any issues with data loss.  Mostly it was just a pain to have to do it and now I'm less likely to buy any refurb again.  I paid $180 and since a new one would have cost 5x that then I guess I got what I paid for!!!
