"I should emphasize again that I was quite happy with my nano and its condition, even with the slight scratches. I don’t think the nano has a problem with being excessively prone to scratching. That said, it was completely amazing that I could remove every scratch with just a little work with Brasso. If you wish you had put your nano in a case before you used it, you now have an inexpensive way to get a 2nd chance."
