I am so happy with my refurbished 2015 MacBook Pro.  The condition is perfect....no scratches, dents, anything.  Setup was very quick....it came with High Sierra which I immediately updated to Catalina.....easy....peasy.  I was nervous to purchase a refurbished unit but my Covid impacted budget couldn't afford the price of a new MacBook to replace my fried one (oops....coffee), so I took the plunge and am so delighted I did.
