I have managed to put a very fine scratch on the screen of my RNS-E unfortunately. It's only visible when the unit is off and under certain light but it's still bugging me. I have seen there are many products on the market for phones/ipods etc such as Displex, iDrops and Applesauce. Also I understand that the screen has an anti-glare coating which is what is actually scratched. Can anyone recommend a product they have actually used on their own RNS-E that should at least make it less noticeable? Cheers!
