I purchased the Waterpic-100 several months at the recommendation of my dental hygienist. During my last appointment, the dentist and hygienist both commented on how well my exam went and I reminded them of their recommendation.
My dentist and dental hygienist suggested I get the Waterpick Flosser and that it would help me...and be easier to use than dental floss strings. They were right. It's very easy to use, and more importantly, very effective.
purchased a month ago, have been using for about two weeks.works fine. do have an issue with leaky water fittings. but unit does what it was intended to do.
