I can't argue with the results.
Everything about these seems terrible to me - the floss is thick, uneven, and saggy, and they're expensive. However, my four-year-old is doing a fantastic job flossing his own teeth with them, better than with the other kid-targeted flossers we've tried. Also, he really likes that these are actually shaped like animals, as opposed to some flossers that have pictures of animals on the bag, but just have colored flossers with a relatively standard shape inside.
