I purchased this laptop just 3.5 months ago, today the built-in screen suddenly stopped working. Apple Care confirmed that it needed to be replaced at a cost of almost $800! I messaged the seller to see if I could get a refund or at least a replacement, but they REFUSED to work with me since I'm technically outside of the 3month window. Terrible customer service and a COMPLETE WASTE OF MONEY. DO NOT BUY FROM THIS SELLER!
