Hey guy's just wanted to ask, does your Magic mouse have any swivel marks or look alike scratches on the top of the mouse where you scroll or the "trackpad" just by normal use. You can see this by putting it up against direct light from a lamp or flashlight and looking at it at an angle. Mine has started to develop them and I just wanted to know if this is just normal usage. Thank you for your time and hope you all have a pleasant weekend!
