    This is a good product but the water container is small and doesn't hold much water. I have to constantly refill it to floss out my teeth.

      Hello Bestbuyfan11 - We are sorry that you are not completely satisfied with the product. This model is designed to be small as it is intended for those who travel and/or have little counter space. Some users may find it necessary to fill the reservoir more than once. If you are finding it to be a hassle to refill the reservoir, a counter top model would be a better fit. We would be happy to help! You can email me directly at smreviews@waterpik.com for assistance.

    Absolutely love this water oil. The only down fall is the water area is quite small. But other than that works well.
