I bought this a month ago. It really gets out the food around my teeth. I've charged it once and it still on t if e same charge. I don't always use it every day. I usually only fill it up once. I also use gum rinse with the pink, sometimes with water and other times straight. I can tell a difference!
Inexpensive, does a great job. First pic I have ever bought. My dentist suggested this would be an easy way to clean between the teeth and gums and he was right!
