It seems like all mouse with Darkfield has this. I bought Performance and Anywhere and both has this. Looking under a magnifying glass, it seems like this looks like a hot stamped mark (a process of bonding one piece of plastic to another using heat)...not sure why this so and I am trying to get the reseller to find out. To me...this is not cosmetically acceptable for a high end product.
