I was really pleased to find this compact Waterpik that takes up so little room on the bathroom sink. It works well. My only disappointment is that it is as disposable batteries instead of rechargeable.
I bought this unit in February 2021 and have always bought Waterpik products. I am so disappointed. The on-off switch is difficult as is the battery compartment cap. Now I have some moldy looking stuff growing all around the cap as well as inside the water compartment.. and I removed the pic and it is growing there also. Gross. I have tried distilled water and vinegar to clean but since I can't access the inside I can't remove the gross looking stuff in there. After less than a year (7 months) I expected more. My last waterpik lasted years. Wish I had just gotten one of those again.. (sigh) I have a dental issue that requires the use of a water flossing product.. I am now at a loss as to what to do.
No, I would not recommend this to a friend.

We are so sorry for the difficulty that you have encountered with your WF-02. It is very important to remember that if you use any additives (such as mouthwash), that you fill the reservoir with clean water and run it through the unit to flush any residual mouthwash from the water pathway, after every single use. Please also keep in mind that cleaning the product, regularly, with vinegar is actually for prevention.
Here is a link to more information about using mouthwash:
I received my replacement today. Bought original June 2021 and it totally quit September 2021. Before it's death, the water chamber lost the ability to click into place and stay on but I was able to find a workaround. Batteries needed to be changed and opened a brand new, unexpired package and it never turned on again. Did all the recommended troubleshooting and called company and voila - a replacement. I suggest keeping your receipt and all paperwork "just in case". Company was easy to work with. Price point of this is great and I LOVE IT. I was just disappointed that it malfunctioned.
