Absolutely love these flossers from GUM. They're cheap for the number that you get, and get me to floss much more regularly. I'm able to get into into my hind molars with much greater ease compared to regular floss. While it's annoying that these are single use, from a cost perspective, these are so cheap per each flosser that it's not a big deal. Assuming you floss once a day, a year's supply would only cost you about $14. Overall would recommend these!
