Received the refurbished HP 600 G1 as expected and just as described. The unit appeared to be new with the exception of the packaging. No scratches or marks outside or inside no dust or any evidence that it had ever been powered up. Set it up and allowed Windows 10 Pro to set itself up and completed with no issues. Followed the steps to activate using the number on the COA Sticker on top of the case. Perfect. Started the update process and allowed the machine to update to current status all went without a hitch. Removed the trial software and added my own copies of Office and Virus protection.The machine is quiet and barely makes a whisper if you get right next to the fan. Fast as well and suites my needs for the internet, mail, audiobooks ... Great value for the price.The only Con I have is that it could or should be better packaged against rough handling. The PC was wrapped in a layer of bubble wrap but the box was too large and it was rattling around inside.
