I bought this a month ago to replace a 20 year old WaterPik. The old one works great but my last pik broke & WP does not make replacement parts for it anymore. I'm in braces for the second time and I can't imagine not having a WP. I use it at least once a day, more often if I'm home, to rinse out after eating. It does a fabulous job in less time than it would take to brush. I had my 6 month check up and cleaning recently. The hygienist & dentist said my teeth were fabulously clean with next to zero plaque, which I attribute to the WP and to a decent electric toothbrush. My orthodontist and dentist both say the WP does not replace flossing, so I continue to floss daily. But for all the non-flossers out there, you really need to invest in a WP.
Love cleaning. Many bridges so great with that. Bought $ model w/most wands so poor design, lid will not close due to extra wands so storage is open & covered w/ziploc, takes up lot of room & store under sink. VERY LOUD. (Have tinnitus, have to use ear plugs. Should provide different top to hold extra wands, like holders in top so lid stay closed sanitary.
This is my third waterpik. I've been using waterpiks for 30+ years. I travel with my waterpik. I use it daily and have great dental exams. Wouldn't be without one!
