Various vendors sell renewed MacBooks, so your experience may be different. Mine came from APLCOMO.My MacBook Pro looks brand new. Not a scratch or ding on it. The keyboard is pristine as is the screen. Guessing the previous owner used an external monitor, mouse, and keyboard and never even opened the lid.  Running battery health app, it has been cycled 300+ times, but still is at 85%, which is fine with me.I'm extremely happy with my purchase and would do it again.
