I bought this a few weeks ago & I'm so glad I did. I had a separate toothbrush & battery operated waterpik. As much as I liked both I wanted to upgrade. After reading the reviews I was sold on the WP-900. I would definitely recommend this product.
My previous flosser had broken and my dentist recommended this one. It seems to do the job very well and flosser and toothbrush are all in one product.
This is my second water pik. I was very pleased with the first one. The brush heads on the new one don't sit flush to the base of the brush handle. It works fine but I was concerned about the gap accumulating debris.
I would recommend this to a friend!

Thank you for providing feedback! A small gap between the power handle and brush head is considered normal. Please ensure the brush head is removed from the power handle and rinsed after each use.
