I like the combined brush, but was disappointed only one came with the machine. I have only used this product a few weeks, I don't know how long they last and have not researched how much a replacement will cost, which would likely impact my review if they are expensive.

I am a Dental Hygienist and I have used and recommended Waterpik products for many years. I really love the SonicFusion. I have seen firsthand the improvement in oral health for patients who use their products. What can be better than brushing and flossing at the same time! Patients with gingivitis or periodontitis will see great improvements.
