I also had a bad refurb experience, two actually. I mean, of course not "every single" refurb is going to be in terrific condition, it's just not possible.
The reason some "slip through" the system is because they're not all checked. It's such a myth perpetuated by members of message boards such as this. If they were all checked, then your 2 poor experiences, and the poor experiences reported by others would
NEVER happen. How could it? Supposedly, they're all checked. That's even better treatment than new machines get.
Apple doesn't check every machine with a fine-tooth comb. They'll definitely check the hardware if it was returned as a DOA unit, if a component had to be replaced first, or if it's a few weeks old and some AppleCare person thought, "Meh, I'll let him return it anyway." However, if someone buys a 15" MBP, opens the box, turns on the machine, but then returns it to Apple immediately for a new 17" MBP, then Apple's not supposed to be able to sell it as new. These machines are sold as refurbs. Are all these returns checked thoroughly? Yes, but most likely, they're only checked cosmetically.
It's really hard to say. However, I'm fairly certain sure Apple doesn't check every individual refurb unit. Their hardware diagnostic test takes hours to complete, and it wouldn't make any financial sense to check a practically new machine that they plan on selling at a reduced price, when AppleCare exists to take care of any problems that would arise anyway.
Though, if you get a bad one, like I did, they offer to exchange it or give you a refund.
True. That's the great thing. They're not "as is". You can exchange it for another refurb if you're not satisfied.
