Works well, pushes a lot of water, compact and convenient. The reservoir usually gets me through two cleanings, and the cable is very useful in keeping things neat. Nice that the toothbrush is part of it -- and it's a high-quality rechargeable brush. Two quibbles: The Waterpik motor is LOUD! And the brush's buttons are a little too close to where my hand is while I'm brushing, so I often reset it by mistake. But they're small complaints. Very happy overall.
I use mine twice a day. Very helpful to flush out between teeth after flossing. I have still seen food particles come out with the water pik, even after brushing with the electric sonic toothbrush, flossing and picking. Has made a difference in my daily denial route.
Efficient toothbrush and waterpik combination. I really like how they are both housed in the same unit. Only think I would change is the 30 second timer that is built into the toothbrush - I wish that could be set differently or turned off. Otherwise it works great after getting used to how to maneuver the waterpik without getting too much water everywhere.
