I think it works great, a little messy at first for a novice. It surprises me sometime, because even after I sometimes brush, it is able to remove hidden food, which is outstanding. I am so happy I made the purchase. I also purchase the case for my extra piks.

We just purchased our first Waterpik, I really love it. It is easy to use and clean. It fits nicely on the bathroom counter. My teeth and gums feel wonderful. It is easier and takes less time to use the waterpik than to use the proxabrushes. I highly recommend getting one

There is nothing quite as satisfying as flossing with the Waterpik® WP-660!

excellent product. im glad i purchased this waterpik.

Love my Water Pik. It removes the debris from my gums that brushing misses
