That's 521 bits for the ECC part, as I read it.  An odd size, even there?
If nothing else, see John Gilmore's preference for non-standard sizes...
(No, I don't know if this product is any good, but I don't think that
this is a prima facie reason to disregard them.  And of course, "521"
is a simple typographical error away from "512", which we all realize
is a magic number but a reporter might now.)
