I've had my new WP-100 for a while & have found it just as easy to use as the travel waterpic I had used for years. Not traveling anymore so the WP-100 is just fine.
We purchased 2 of these Water Piks Love them. Bought each in Black, has 10 settings, all the different attachments. Our Dentist recommended this brand .
I have been using my water pic for about a month now. I don't think my gums have ever looked this good. It is easy to use and comes with a nice selection of tips.
