Review (5/5): Not manufactured any longer/Sadly product truly out of production/What a shame.  Best flosser made.
I believe this product is no longer manufactured. I am a dental hygienist who loved this product and have asked the Oral-B rep about getting refills only to learn they are no longer available. Thought I'd try Amazon and when I realized they aren't even available there I thought I'd just enlighten others of why.
