Negative Positive
Title: simple concept, HIGE benefit
Review: Although yes, the concept is rather simple- just spraying water with force to rinse food particles out, it works amazingly well, especially for people with gums issues like I do. My gums bleed whenever I floss. Waterpik actually gives me an alternative solution to that issue. The manufacturer is also great for making a top quality product. I have been using this for a year and my dental health has improved a lot.
