It's been over a month that I received my WP-100. This was my first purchase of any water flosser after being advised by my dental hygienist for 2+ years. I had always despised string flossing because of the sensitivity and bleeding it brought onto my gums, and I never felt certain I was even flossing correctly. The WP-100 is convenient and easy to use - it alleviated all my flossing fears and has me on my way to long term complete dental health! I love water flossing!
This water flosser effectively removes food particles between teeth that brushing misses. I would have rated it excellent except that when I first used the unit, there was a large water leak from where the handle hose exits the main unit. Installation of a new handle unit completely solved the problem and I have been very happy with the unit ever since.
