I purchased a refurbished 2019 Macbook Pro (A2141). Works fine, but there were some wear on the palm rest area, and it really bothered me (see before photo). I was close to returning the machine (yup, it bothered me enough that I would return it), but I looked up if this sort of product existed, and I quickly made the purchase.I pretty much had low hopes, but I figured it couldn't get worse than what I already have. I was pleasingly surprised. It was jaw-droppingly impressive. See AFTER photos.I don't know what the material is made of, but I tried scratching it with my nails, and when I applied it to the surface, I used my credit card to make sure there were no air bubbles, and there were no scratches were made at all. -- The one thing that was tricky is if you kind of bend it, it will crease, so be VERY gentle, and apply SLOWLY. My AFTER photo does have a keyboard protector on it as well. That's why it looks different from my BEFORE photo. The color match is not precise, but weirdly I like the color of the adhesive better than the original surface.Happy I made the purchase. I feel better about keeping this machine. Value is great. I will update if there are any future wear and tears.
