only okay
These flossers worked better on my daughter compared to the DenTek Fun Flosser, but still were not easy to get between my daughter's teeth.  I've switched to Glide floss using my hands rather than a flosser, and it is much smoother and faster, better for all involved.  If the floss on the Plackers Kids 1st were of higher quality (smoother), then these might be better than using my hands, but unfortunately it is not.
