The Waterpik is a great product. I helps get the extra food particles that flossing missing and leaves your mouth feeling really clean. It had ten power settings for different mouth sensitivities, so it's family friendly. .
This flosser has a good range of speeds and a variety of tips. The only down side is that the reservoir could have been larger. I need to fill it twice each time I use it.
I'm very pleased with my WP-100. It's so powerful that I have to have the setting at about 1/2 power. My teeth feel dentist clean each day as I use it regularly. I have 2 bridges and this waterpik cleans under the "teeth" better than flossers. Highly recommend.
