This is the 3rd refurbished PC I have purchased in the past 3 years.  This one happened to be for my father who was sorely in need of a technology upgrade.  The unit came exactly as advertised.  I realize these are most likely used units that have come off a lease to a corporate office somewhere.  The unit was clean, in good shape, some visible wear but no frank damage.  I booted it up as it was delivered to me and everything worked as advertised, including the Windows 10 activation.  I contacted tech support for information as I intended to upgrade the hard drive and received both a phone call message and an e-mail explaining what I needed to do to get the Windows 10 Pro activation on the new hard drive.  (Thank you for the great tech support!)  Then I installed an SSD, linked up the digital Windows 10 Pro activation to the new SSD (no more activation keys used) and the unit was ready for my father.  Once he received it (mailed to him out of state) he has been thrilled with the upgrade.  So far, no issues whatsoever.  Just realize these are probably previously well used leased units (this one's hard drive had 61,000 hours on the hard drive in it - which is almost 7 years of run time) most likely with lots of life left in them for the average user.  I'm currently running another refurbished unit, that I processed in a similar manner, in my office for going on 3 years now, and that unit is left on 24/7 for remote access.  For around $200 bucks, with a new HDD or a SSD upgrade you can do yourself, these are a deal.  I hope this is helpful to someone.  Warm regards.
