The device was delivered per the expected date.I powered up the device and got a screen stating I needed to reinstall the OS.  I am not doing any kind of work/troubleshooting on a device that was sold as "excellent condition and thoroughly checked".Cosmetically I expect some nicks or scratches.  I do not expect to have to reinstall the OS.Now I have to pay to send an item back that does not work?  I will never order from this seller again.
