Purchased new around 2018-19, still works fine. Cosmetically there is a small discoloration or possible de-lamination (?) on the screen, near or slightly above the center. you can barely see it when the screen is on (with most settings), but it's noticeable definitely with the unit off. I've tried to show it prominently in picture #2. The touch screen still works fine in this region, so I'm unsure of the effect beyond cosmetic.
