Buying a used MacBook Air retains some value but also presents some risk. However, buying a refurbished MacBook Air is the safest route as you will have a perfectly functioning laptop that should last many more years, and at a cheap price! At Back Market we don’t simply sell a used MacBook Air without doing the necessary quality checks. We in fact do rigorous testing and replace parts where necessary, to ensure the refurbished MacBook Air works ‘just like new’.
