It would have been good 4 or 5 years ago, and cost about 3x that.
Usually refurbished units are a great buy if you don't need top spec performance.
The only downside is that in another five years it will be getting really old and might struggle with some everyday programs which have gotten ever more demanding e.g. youtube default becomes 4K with 6K options.
That might not matter but you get the idea.

I would still buy it as a second unit though
It might already struggle a bit playing 4K video, and any video editing or dealing with large photo files won't be too snappy..
