I've owned a number of WaterPik over the years. The WP-450 is the best design of them all. This model has a clear fluid tank, allowing users to know when a refill is needed.The ergonomics are vastly improved with a shaped grip. The high/low selector switich lets users adjust the intensity of the fluid stream. If I had owned it longer, the rating would be excellent.
Bought this on the suggestion of the dentist. I have found it to be of very limited use.
No, I would not recommend this to a friend.

We are sorry that you are not happy with the product. Perhaps a link to our how-to video would be helpful. It does offer information on how to use the product to get the most out of it.
I bought this waterpik to replace a previous handheld one and the new one is very loud when running. I live in an apartment and the people next door probably know when I am using it! I do like the various attachments, especially for cleaning crowns and bridges.
