Quality clickbait.
I've only ever put protection on the top screens of my original DSes, when the sensitivity was already so low that putting an extra layer on top of that was suicide. Maybe it's better now. IDK. I don't play lots of touch screen-based stuff, and doubt that I'm in the minority on that, so I'm sorry I can't really help you. Try checking Amazon reviews or that sort of thing, and if you do end up going for it, please give us your impressions.
