I have a DS Lite and when I got it bought the Hori screen protector to put on it. I used this Hori cleaning cloth for the DS Lite to get rid of dust before putting it on. This cloth is very soft and wouldn't scratch a thing. It didn't scratch the DS Lite screens at all. I just got my new PSP. First thing I did was get a Hori screen protector for it and before attaching it I used my cloth to very lightly wipe off the dust. Thing is, I scratched the screen like 3 times. I wiped EXTREMELY lightly and to my shock I see these scratches. They're light scratches but pretty big and it's really p***ed me off. I'm just really picky about these things... The Hori screen protector is more scratch resistant than the actual screen.. The fact that I gotta touch the glossy faceplate to use the PSP is gonna drive me insane cause of fingerprints and the fact that I'll always be worrying about scratching it... Some of you probably think I'm sad..
