I was disappointed. The unit is cumbersome to hold and use. I plan to buy a new water pick and use this for travel. The pressure settings could be more user friendly. You have to hurry to clean your teeth before a refill is needed. The idea is great but I feel the design needs more refinement.
If you have any dental work these Piks are a must! Around the crowns, bridges, braces just Feels so much cleaner! Very glad my Dentist recommended I get one! I left his office and went and bought my 1st Pik! A very wise purchase / investment!
