"certified refurbished" - yea, right. It's not. The battery can't hold a charge at all, and every time I turn it on I get a loud beep and an error message about how the battery's so degraded that it won't work. Amazon won't let me request a replacement, or do anything about it except tell me to send it back in for a refund and buy a new one - which of course is conveniently more expensive, because this has gone up in price $50 over the last two weeks. Would give zero stars if I could, for both the product itself and the "customer service" around refurbished products.
