I bought this one a month ago to replace another travel one that had a larger container to hold the water and was easier to fill. I still prefer the larger base model if only it didn't take so much counter space in the bathroom.
I'm very please with the results this product provides. As a first time user it took a little time to to become comfortable with using the unit, but in a very short time this has become a part of my regular dental care routine.
I bought this water pick 2 weaks ago because a dentist recomendation. I'm very happy i did it. It's easy to use and clean perfectly whatever food is left between the theet. Excellent product.
