A little bit of grass Panasonic ultrasonic rinser home white one, has it ever been used?

Last year Panasonic in the domestic on the ultrasonic rinser EW1611, ultrasonic water flow compared to pulsed water flow, the sense of impact on the oral cavity is smaller, but the cleaning power is better, the first few times you use may be a little bit of bleeding, the back will not be, the ultrasonic water flow bubbles are more fine, through these fine bubbles composed of water flossing, can shuttle between the teeth, bursting to produce a strong impact, thoroughly stripped of dirt. Even the back of the teeth, which is very hard to reach, can be rinsed. There are two replaceable nozzles, so the whole family can use it together. With a large 600ml removable water tank, it can be used for 120 seconds when filled with water, so you don't need to refill the water twice when cleaning.
