I received this product and the battery held a charge for less than 3 hours. Was on with Apple Care service for over an hour to run various tests and fixed, which improved the battery life for up to only 6 hours. Requested a replacement from Amazon, which I received promptly, and it had the same problem. Went through the process again, and ultimately decided to return and cancel the order. Then, the refund took about one month! When I finally got through to Amazon customer service, the attendant was very helpful, but overall this experience was quite frustrating. Would not recommend buying an expensive device from Amazon.
