I bought this because i had not been to a dentist in 30 years. No kidding. I have gum disease and they actually recommended this exact product. I read about it and bought it. All I can say is WOW! I have never felt my teeth so clean. The combination of jet and brush is amazing. I so wish i had done this sooner. I mix anti-plaque mouthwash with in the water container, and the places where I could feel plaque build-up on my teeth with my tongue are now as smooth as glass. Again, this thing is amazing.
I'd been reluctant to get in the Waterpik flossing world, especially when it required two different electronic devics for brushing and flossing. But when I found out about this new combined device, I was ready to go. It works very well, although I do not do the combined cycle, keeping brushing and flossing separate, but it is still very convenient. It's not a bad looking unit on the bathroom counter, and I MUCH more enjoy this flossing approach vs the dreaded floss twine. Highly recommended.
