With today’s 10% off in the app discount, a pretty good deal. I’m not convinced that the Floss Action heads are any better than regular, but when I can get them at about $4 each (Woot or Costco ) I don’t feel bad using them 3x a day and replacing regularly.
Pro tip: wash weekly with warm water & Castile or antibacterial soap, rinse thoroughly, air dry. Brush out any loose bits with another toothbrush. They’ll last longer.
