As someone who has never once needed to return a refurb, but has needed to return multiple "brand new" machines I'd disagree.en subject to liquid damage? Apple understandably wants to save money, but refurbished is definitely not equivalent to new in reliability.
Refurb devices generally go through a-lot more vigorous testing than brand new machines, and most electronics these are not likely subject to multiple component failures.
Is there any hard numbers on refurb devices failure rate vs new?
Even brand new devices can end up "repaired" when then are tested prior to assembly, and minor issues are identified e.g. bad solder joints. They would go back for re-work. Couldn't that also classed as refurbished ?
HOWEVER
I think there should be a fair cutoff period where a refurb should be accepted by the customer as a replacement. For example only devices outside of, let's say, 6 months should be replaced by Apple with a refurbished device.
If a device is under 6 months old but discontinued or out-of-stock. Replacement with the current equivalent would be a fair deal.
