We replaced a classic with this model after our tank broke. This model is quieter with great pressure. The small footprint fits well on any counter. Two complaints, the unit is so light weight that when empty takes two hands to turn the power off, one to hold the unit and the second to throw the switch. Second complaint is the hose could be 6 inches longer. All being said, we are happy with our purchase.
The WaterPik-100 is just what I need to provide powerful flossing in hard to reach areas between my teeth. I have used all attachments and find the plaque buster tip to be very useful. My teeth feel clean and my overall dental health is improving.
The Waterpic WP-100 works well for me. Water tank lasts as long as needed, and I like the option to regulate water flow to my comfort level. Fairly new, and so far I’d say well worth the money
Always wanted to try a water pik but now with my periodontal disease it was more important than ever. This works really great - after a few days I got it down with water shooting everywhere. ,)
