I'm not a fan of the Rexy fobs although I know that I am in a minority and that they are very popular, but in some pics they look so big in comparison to the bag. They may be hanging below the bottom of the bag - or look like they are walking next to the bag when it is sitting on a table.
I love decorative fobs but I still want my beautiful bag to be the center of attention with the fob as an accent. With some of these really large fobs it looks like they are competing with the bag, not complimenting it - but that's just my opinion.
