This laptop (Dell Latitude 5591) looks, feels, and behaves is if it is new from Dell! I can state this as I received my work laptop (Dell Latitude 5590) as a new device.  This seller did amazing work refurbishing this laptop.  I purchase this particular Dell Latitude model for personal use based on my experience with my work laptop.  I could not be more pleased with this purchase. The condition of the hardware is superior - like factory new.  The Windows operating system installation is also superior and stable. I have seen other laptops that claim to be refurbished, but the OS installation seems questionable.  This is solid and legitimate.  I waited a couple of months to write this review as I wanted to be sure my first impression of this laptop held up.  And it has.  This machine is reliable and stable.  I would have no hesitation in purchasing from this seller again.
