I was highly recommended by my dentist to purchase one of these and I'm sure glad I did!! It's just an amazing machine!! It's so reasonably priced for all that comes with it. I've had it about a month now and I can feel a HUGE difference in my mouth and my gums from the water action. I use it everytime after eating so I feel I have a really, really clean mouth. The attachments are great and have a variety of uses. I LOVE this thing and would highly, highly recommend it for great oral hygene. It takes no time at all too use and works SO much better than "normal" brushing.
