They’re a Gamble
Apple’s certified refurbished devices are no more of a gamble than a brand new Apple product. Before selling any certified refurbished device, Apple meticulously inspects each device. In fact, because they’re individually analyzed, they may be less of a gamble than a brand new device.
Of course, that only really applies to devices directly by Apple on its Certified Refurbished storefront. We’d highly recommend avoiding seller refurbished devices, like those you may find on eBay or Amazon. Unlike Apple’s refurbished offerings, those devices may actually be a gamble.
