We just got this and I love it! It took the struggle out of flossing for us!
If you go to you can get a free starter!

i do have to admit that it is a handy little tool (my bf bought one under my protest) but anything with the word disposable makes me shudder!
there are other tools out there that are a little bit more bulky but act as a holder for your floss that work just as well with less plastic making into our landfills.

Well, after 6 yrs of using cloth diapers, I feel OK about using little disposable plastic fossers if they make flossing my kids teeth a breeze. Their teeth are unfortunately spaced close together, so regular floss is really difficult because it tends to be thicker.
I'll have to check out the other contraptions though...if they work great, better for the environment and I can find a thin floss...I'll definitely choose that. It's cheaper too.
