I like this product, except if you use it on anything other than low, you have to refill the water storage at least once. Med., once, High, at least 2.
I would recommend this to a friend!

Hello dspi- Thank you for sharing your feedback! We’re glad to hear you like the Cordless Advanced overall. Higher pressure settings do use more water, but the good news is the reservoir is quick and easy to refill, so you can continue your cleaning without hassle. We appreciate you taking the time to leave a review!
The travel version works much better than I expected. I love how clean it leaves my teeth feeling. Having this one helps me be more consistent in using it.
Just too small of a reservoir and not enough power

This is a very nice looking flosser. I love the color. However, the tank just doesn’t hold enough water and the psi, power just isn’t high enough. I had to return it. Sadly, I also returned the attachments, which I could have kept because I ended up buying a countertop model that came with another portable flosser. I’m happy now, although I do wish this one would have worked for me.
Liked the other model better. This one doesn’t have much power.
No, I would not recommend this to a friend.

My Dentist and Dental Hygienist have been after me for 2 years to use a WaterPik product to reduce plaque. I found a good deal on this unit and have discovered I LOVE using it! I love how portable / small footprint this product is. Furthermore, My gums and teeth feel amazing after using this product and I look forward to my sessions after brushing. Well done WaterPik!
