Bought this item to replace old system.  Wasn't sure about a refurbished product but could not resist great price.  Install was easy and no problems were encountered.  Took about 30 minutes and I was connected to my home network and the internet.  Not a fan of Windows 10 but will deal with it.  Did not really have to call for support so really could not comment on their efficiency.  Product was delivered next day, can't beat it.
