I read the reviews for this and several of them stated that there were scratches on the outside that were glaring and did not deserve the description of "excellent".  So, I looked up Amazon's definition of excellent in refurbished items and it said that any cosmetic imperfections would be so slight that they would not be visible from 12" away or more.  I decided to order one (because I really wanted a Surface Book 2 with aq 15" screen) and waited for it to arrive.  Much to my delight, it was flawless, not even a hint of having ever been used before.  Setup was easy, and everything is working as hoped.  It comes with Windows 10, but during setup, offers that you will be able to upgrade to Windows 11 at no cost.I am totally delighted with what I got, and the only thing left is to see how it holds up.  As long as I have not updated this review, it means that all is still going great!
