I remember having a distinctive moment of clarity watching Seinfeld reruns in 16:9 HD. Did they have the foresight that it would be a classic making billions in syndication?
A piece of hardware that has been re-certified has absolutely been through more extensive testing than those sold as new, its a simple fact of the matter
There's a similar tenet for purchasing refurbished hardware. The supplier only wants to stomach a single RMA, so they will put in the effort to make sure the re-certified doesn't ever come back.
