WARNING STAY CLEAR FROM ORDERING FROM TECH EXCHANGEE!!!Laptop came in a Fedex cardboard box. NO bubble wrap or anything else to protect it from damage. Upon trying to start the MacBook Air  for set it, it did the hello screen but within a few seconds it went to a black screen. I ordered on a Thursday and received the very next day. Within 24 hrs of me ordering. Took about 48hr before I got a reply back. I requested a replacement. Shipped that MacBook to them on Monday and they got it back on a Thursday. Instead of issuing me a replacement they just issued me a refund. Poor customer service. When I asked them why they issued a refund instead of a replacement I was only told we are sold out. If they were sold out, why couldn’t they have told me that whenever I requested a replacement they could inform me hey we’re sold out. We can issue a refund we’re sorry for the inconvenience, no they didn’t do that so, please stay clear of them.
