Excelente pero mal en embalaje y cable
Excelente compra, la verdad esta como nueva, parece recien comprada de la tienda oficial pero el embalaje deja mucho que desear, perfectamente se pudo haber dañado pero no, y bueno otra cosa es que demasiado mala calidad de cable y cargador, minimo un cable genuino hubiesen puesto pero por dicha ese no es un gran problema.

Is this really refurbished? Practically brand new
Practically brand new. Only difference is the charger/cable are third party and no apple box. I can forgo the Apple unboxing to save a few dollars.
