Charging cord was very inconsistent.  Very difficult to connect with a customer service rep and when I did, they told me the chromebook was out of warrenty even though it had been purchased less than 3 months ago.  Redirected me, to another department that would take 3 days to verify that it was under warranty despite me sending them an invoice with date of purchase.  Very poor customer service from Samsung and will probably never purchase another product from them.
