Thought I had ordered the recharging model which would have been better. Dental assistant recommended such treatment for those of us who fail to adequately floss. My teeth feel like they have just been cleaned after a water pick treatment.
I received this model for Christmas. I like it. The only thing it needs are detailed instructions on how to clean it, when to clean it, and when to replace the tips.
It seems to work well but even the low setting seems a little strong when you start. Rather than the off/low/high switch, there should just be a momentary on/off switch to hold, and another for the strength. Overall it is okay.
I have an electric waterpik, but needed one for travel and this is ideal. It works just as well as the electric and treats my teeth and gums as I need.
