My kobo pen scratched up my libra color screen but it's only noticeable in the light/sun. I really wanted to annotate with this ereader but after I reached out to customer service they kinda told me that the kobo stylus isn't meant for the libra color. They did offer to replace it but it's gonna take over a month. I read so much and I don't want to be without an ereader but I mean that's no big deal, the big deal is that I bought this ereader to annotate! I hate that they marketed the stylus as an accessory for the libra color. I'm just annoyed and disappointed even tho I love my kobo
