The unit operates fine and seems like a decent machine for the money - but one of the big factors in my purchase decision was that the add description listed WiFi, I assumed this meant built in WiFi (No Ethernet hook up at my work station) and this unit DOES NOT HAVE BUILT IN WiFi.  Instead, it uses a cheesy WiFi dongle that drops signal dozens of times per day.No one likes a dongle getting in the way when they're trying to get work done..AMAZON.
