The Switch console itself came in perfect condition.
There were no signs of scratches, blemishes, or that the console had been used at all.
The controllers also arrived in perfect condition.
There was no indication that anyone had used these controllers before, at all. If they aren't new, they could easily pass as brand-new.
The only thing that showed signs of use was the back of the dock.
There were a few light scratches on the back of the dock, inside the recessed area. These don't bother me at all, as the only time I'd ever see them is when I plug in the cables into the dock.
Otherwise, the dock's front is completely blemish-free and also looks brand-new.
As for the cables, they appeared new rather than used. It's not clear if Nintendo replaced the cables with new ones in refurbished Switch units.
Best of all, the entire system works flawlessly.
I've only been using the Nintendo Switch for the last week, and I haven't run into any problems at all.
There's always the chance that something could break or stop working properly on my Switch, but Nintendo's refurbished devices come with the factory one-year warranty should anything happen in that first year, just like a brand-new model.
