Works well. Really makes a difference in cleaning between teeth. Good stream of water. Seems durable.

This works great, and the newer design (compared to the very old one I’d used) is much easier to use. I like this much more than the handheld version, since it holds more water and is easier to use. The sale price made the difference, and it I love it.

I was influenced to get the cordless Waterpik annd I’m so happy with this amazing product! It leaves my teeth and gums feeling incredibly clean. I’ve never been a flosser because it’s a pain – this is the perfect solution. I would like it just a bit more powerful but it works well. Easy to use and dentist-approved—worth every penny and much more convenient.

This water flosser was replacing a very old version of the same type. It’s easier to fill than our old one and does the job. There is enough water in reservoir to do a thorough job. We like all the flossing tips provided. It has two flossing modes flossing and hydro-pulse massage. We just use the floss mode which works best for us. It is a great purchase.
