I love this product. It's only fault is being a little loud. I tried another brand. It was quieter but I don't think it did as good a job as the Sonic. I went back to Sonic.
I love my new waterpik, it makes my nighttime routine so much easier and enjoyable, it’s a toothbrush head that does both work and the pick part is soft but more efficient than the old sharp type that hurts your gums sometimes. When you turn the switch to brush your teeth, it’s soft , gentle yet does a good job. The only thing is the price is overpriced.
