The manner in which it was described to me is that cosmetically, it is near perfect if not perfect. The vast majority can't be distinguished from brand new. On a lot of models, the cases are completely changed out as that is the cheap part of the phone. However, the casing on this particular model is more expensive than other phones as it is supposed to be a rugged phone with Gorilla Glass and a more durable build.
I haven't ordered this particular phone but all the refurbished cell phones, computers, etc. I've purchased in the past that were refurbished or reconditioned have been perfect; just like brand new.
However, maybe somebody who has actually bought this exact phone refurbished can chime in and let us know their experience.
