The laptop itself works fine, but the charger they sent doesn't work. I called customer service,  and they just put me through the runaround when all I was asking is that they send me a new charger that actually works!  But that is too difficult.  That girl kept putting on hold because she wanted to have a conference call with Samsung???Buying Amazon Renewed means they were supposed to go through all the components, and ensure they work..  They are also supposed to standby their Renewed products and immediately fix problems... "100% Guaranteed" all they did was play pass the buck, and then said oh we will give you $20 Amazon credit and you can go find a new charger yourself...
