Negative Positive
Title: Useless
Review: It seems like they never tested these. It takes 4 or 5 to do my mouth as the floss stretches, shreds and breaks lose. Last night the plastic posts that hold up the floss broke most of the way inwards leaving plastic shards in my mouth! My housemate had two similar experiences. We haven't had such problems with with other brands, but the drug store never seems to have the same brands each time I visit!
