Negative Positive
Title: Read before you buy...
Review: For some reason, Amazon is marketing these things with the 505 reader. They only work for the 500, so do not waste your time and money. Sony has not yet released one for the 505. You need to check the same thing on the covers as well...if they are for the 500, they will not fit the 505. Otherwise, I am sure they work just fine with the 500...just don't make the mistake!
