VERY SIMPLE! DO NOT BUY THIS THING.After less than a day of using the laptop,just updating windows 10 A blue vertical line appeared on the screen. Clearly a defective screen.No one really cares about customers buying a laptop from outside the US. Do yourself a favor and DO NOT BUY THIS ONE. YOU GET 0 SERVICE.I've  waited a whole year to "Black Friday" to buy this one. Imagine My surprise Getting a unit with a defective Screen.I haven't even started enjoying the "GAMING LAPTOP" BECAUSE I GOT IT WITH A FAULTY SCREEN!! YOU CANT PLAY GAMES OR EVEN SURF WITHOUT SEEING THAT ANNOYING BLUE LINE!NEVER GOING TO BUY ACER AGAIN.
