I just purchased this and this will be my last renewed/refurbished Apple product as it's not the first one that has had issues. I just got this today and it doesn't charge when plugged in at all. The MacBook doesn't even acknowledge that it's plugged in. In addition to that, as I was not able to charge it at all, it did come with the MacBook fully charged, but the charge only lasted about 2 hours with only brief internet browsing. Avoid at all costs and just buy them new.
