Review (1/5): Cleaned well for less than a year until battery won't charge
The H2Ofloss is a major disappointment. It worked well as far as cleaning. But, it has lasted less than a year and will no longer charge. When it worked, the location of the button for controlling the strength of the water stream was a problem. Either the device can be turned off by accident or the strength of the stream can be accidentally increased to an uncomfortable and undesirable high level. Also, the water chamber leaks.
