This is the second Waterpik I've bought in about 3 years. The hose on the unit broke but instead of replacing the hose, I bought a new unit. I'm glad I did. The entire new unit is lighter in weight than the old. Both units were/are pretty easy to use. Would give it 5 stars except, like the old Waterpik, this one is just as noisy.
I got braces recently and flossing was almost impossible in my small mouth. Tried the waterpik and could not believe how much food sediment this dumped in my basin, even after using a pre-brushing rinse and brushing my teeth with either a soniCare or Oral-B brush. This is the best!!
