There is a good silicone anti-collision tooth nozzle to avoid the user ingesting too much microplastic particles. However, it is not a right angle, so it is not convenient to spray wisdom teeth and posterior molars. There is no cross or meter-shaped end drain and pressure relief notch design, so it is easy to leak inside when accidentally withstanding the gums. Well, it is claimed to be an air bomb. Is it the working principle of compressed air spray similar to diaphragm pump and passive spring plunger pump? That is, there is no need to worry about internal water leakage. But that kind of design has higher explosive power... Users with sensitive gums may not be comfortable with medium pressure, while low pressure has no significant effect? Or is it a mixed gas design similar to German and Japanese Venturi effect pipes and semi-permeable membranes? That kind of design requires a pressure relief gap to be insured, right?

This kind of design thinking, feel too simple, at most do a modeling difference,

This kind of charging method is the most annoying. As soon as it gets into the water, it will be abandoned soon.

Does the visual sense of the opaque water tank look heavy?

typo

The real object looks better than the rendering

Good design, 399 a bit expensive

really good

not bad

I think I need this

Different from others

This kind of teeth can be cleaner.
