I WOULD NOT BUY FROM THIS SELLER AGAIN........I purchased a "refurbished excellent" 2017 MacBook Air.  The hinge for the screen was a bit loose and there was a warning saying the battery needed to be serviced.  I tried contacting customer service numerous times and they NEVER responded.  I will was willing to live with the loose hinge if they would refund an amount equivalent to buying a new batter off of amazon but the support team never responded. I will return this and look elsewhere.  I WOULD NOT BUY FROM THIS SELLER AGAIN.
