i've heard of this spray that you can get to spray on it thatll protect the surface better and help reduce glare too. i also bought that hardcase thing to hold it in, makes it a little bulkier but so worth it since i keep it in my backpack with alot of other gadgets that could 'hurt' it
You should really get a little pouch to put it in if you have such a expensive handheld The little carrybag you got with it is good, but the Logitech protect gear is even better!
