I normally never buy second hand, or refurbished tech, but the warranty and price over the cost of a new unit with same features led me to take a chance.  I have to say, so far I'm very pleased!  Item arrived on time and we'll packaged.  You will not get the paperwork you would with a new unit. Setup was simple and fast.  Everything I needed was carried over from our other computer. The I7 processor he makes the unit lightning fast. The only regret I have is the unit did not have an HDMI port.  Time will tell if what I saved buying refurbished over new was worth the savings!
