I ordered a MacBook air (2015) in September. At first, I loved the computer! I had never owned a Mac before because they were too expensive, but I decided to splurge for my schooling. After a couple of weeks, the battery started to last only 4-6 hours. I checked the battery condition and it told me that "service was recommended." Then, I checked the cell cycle count (how many charges your battery has). The number was 800. I thought that it had meant that I had 800 charges LEFT since this was supposed to be a new battery. Come to find out that is the number of cycles that, that battery had already been through. The battery is usually done by 1000, so no wonder I was getting a service recommendation. I was furious that I spent 600 dollars on something that was FAR from new. Thankfully I was able to contact the seller and send back the item for a full refund (that came in around a couple of weeks). I am very thankful that I was able to get my money back. I eventually was able to pull together around 900 dollars for a new laptop. Even though I had to spend more than I wanted, it was definitely worth it to buy a new mac. Please consider the option of buying a new laptop before taking the risk of buying a refurbished laptop!
