I've been using this same computer for a year that was borrowed from a friend after I was laid off December 2021.  I had been dragging my feet on buying a new Macbook Pro b/c the 16 inch is so expensive new.  I ended up buying the same unit via Amazon's refurbished/used program and I couldn't be happier.  It wasn't in the original packaging, but was packaged very well in transit.  I just swapped this unit out with the borrowed one and this laptop is legit!  The owner of the prior one, who works in tech in the Bay Area, was astounded at the price and the cleanliness of the unit.  I don't need the computer for fancy design work, or anything like that, but I really enjoyed the year I spent with the prior Macbook Pro, and I'm beyond pleased with this one at the price.  I figured i was already using a used laptop in the first place and this should be no different.  Plus, this has a 90 day return policy, which basically sealed the deal for me.  The only negative is that it has a slight ding on the lid - I emphasize slight - see photo.  It's just aesthetics and if it really bothers me, I can throw a sticker on it.  That said, it doesn't bother me one bit.  If you are on the fence about buying one of these used units and don't care if you have the latest processor, etc, this is a legitimate steal.  You will not be disappointed.
