The water pink was easy to use but the water tank capacity was smaller than I expected and had to be filled twice for a good cleaning of my mouth. It did a good job of getting the food particles out from between my teeth. My only concern is the water tank is hard to clean and completely dry out.
This Waterpik model is easy to use. This is a charger model; so there is no cord to fuss with. It performs its job very well and does everything we expected it to do.
I bought this a few weeks ago and I should have bought it a year ago when I got my braces on. This water flosser gets everything out between my teeth that I can't see. The first time I used it there was so much food coming out and I brushed before I used it. I will continue to use it when I get my braces off. This waterpik is awesome and my new bestfriend. I wish it had a traveling size so I can take it with me.
