This product uses too much battery. Not efficient for electricity.
No, I would not recommend this to a friend.

We are sorry to hear that you were not happy with the product. The average customer will replace batteries every 6-8 weeks. How long the batteries will last is not only determined by the type and quality of the battery, but how often the unit is used as well. If you use the product more than once a day or if multiple people use it, we recommend a counter top model or a rechargeable unit.
I know flossing is good for your oral health. I also know that at 64 years old I will never change my mind about string flossing. I hate doing it. The Waterpik WF-02W010 is easy to use & does a great job of flushing your mouth clean. If you purchase one don't bother putting in the three pack of Waterpik batteries that come with the unit. They will only last a few days. Install some new name brand batteries and you'll be good to go. EXTRA!! As you don't need electricity I always bring it with my while camping. You're going to love it!
I must be doing it wrong because it’s way too strong for my teeth they bled at first but it was okay afterwards I went back to regular flossing. But it definitely did it’s job
