Better designed tank
This is my second waterpic. The first had the water input door at the bottom of the tank so when the tiny door clip failed I had to toss it. I wasn't so sorry as it was also difficult to clean the tank. So started search for a new pic. Wasn't easy to find a design with water input door at top of tank, also with better door clip. This one is great,  easy to clean, easy to add mouthwash to water. Water flossing is so much gentler than floss. I usually use it in the shower as it can be messy, use warm water and Jason's mouthwash or colloidal silver for a lovely clean mouth. So easy.
