I was originally very pleased with my purchase; GREAT price, great product, great shipping time- then I opened the box. My Apple MacBook Air 13.3 inch laptop was in perfect condition. UNTIL, I turned it on. To my disappointment there was an error in the start up disk- the operating software was not installed and could not be reinstalled. Meaning beautiful computer that would not work, AT ALL. I had to then cancel my order and send it directly back. I was disappointed that there is no replacement program for this purchase- I could believe with a refurbished product that there are occasional mishaps.. but to cancel and then place a new order seems a calculated risk. DISAPPOINTED.
