Review (5/5): A terrfic item that is handy, clever & actually works
This is my second purchase and I can't say enough about how simple & effective this gizmo is at getting little food particles my toothbrush misses. It's more fun than flossing and works just as well.
No batteries or electricity. I fill it up with a combination of mouthwash and water and am amazed at how efficiently it works. It's so good that I keep the second one at work for when I get back from lunch.
My biggest suggestion though is to buy one for the kids. They will love using this little "toy" before realizing that it's doing something good for them. And filling it with plain old water will do just fine, too.
