I originally purchased this item, knowing it is renewed. I needed an affordable MacBook that had more internal memory, RAM and a faster processor than the current model I own. I recieved my MacBook within days of the order, but it had a battery service issue from the start. I contacted the seller and they responded back in a couple days but guarenteed a quick replacement as soon as I followed Amazon's return process and gave the seller the tracking info upon releasing is back to UPS to ship back. Within 3 (business) days, I had the replacement delivered. Same technical specs, in great condition and this replacement has shown no battery issues. I've been a MacBook user for years for video editing, so I may be biased but my rating is due to the customer service and quality of renewed product. Thus far, my experience is great.
