Water pressure is not strong enough. Needs to be filled repeatedly. Corded version is superior.
No, I would not recommend this to a friend.

We're sorry that you are not completely satisfied with the product. This model is designed small as is is intended more for those that travel and/or have limited counter space. Some users may find it necessary to fill the reservoir more than once. Although the highest pressure setting is not as strong as our counter top models, it actually does not make it any less effective. However, we greatly appreciate your feedback and will pass your comments on to our Product Design Team.
Device works great but the tank is too small compared to another brand I used for years. I have to fill your tank 3 times to achieve a similar run time.
This Waterpik works great and does a good job. The problem I have is it goes through batteries extremely fast. If I would have known that I would have purchased one with built in rechargeable batteries.
