Lid itself needs to snap shut. Hose needs to be more flexible, difficult to stretch out to use. Other than that, I like the unit. Performs as advertised.
I got braces 2 weeks ago and purchased the WP-100 to help me with keeping my teeth clean. This was a fantastic purchase. It is excellent for keeping your teeth and gums clean and healthy. It’s very easy to use and comes with 6 accessories. Flossing my teeth has never been easier. I love my waterpik, wish I had purchased earlier.
