Review on WaterPik WP-660 Aquarius Professional, white by Firash Hakimi

The power of the jet at first seems excessive (painful sensations in the gums). But comfortable pressure is easily adjusted, and then the gums get used to the maximum pressure. Until I understood why so many nozzles. One is enough. I didn't rate it for "cleaning efficiency". Because I don’t know how to evaluate it: it’s too subjective, people have different teeth and different food . I didn’t rate the “Modes” of work: I tried different ones. It turned out that for an effective assessment, the default mode is enough for me.
