For many years I use oral irrigators. Always those with stationary water tank, tube and mouthpiece. For about 12 months, the model EW1211 Panasonic and am very satisfied. The operation is very simple, as is the handling. At first I could not cope with the amount of water, since it is but a little small. But more does not allow the built-in water tank. But the amount of water is sufficient. And if not: simply and quickly fill the water tank again and the "second round" can begin. The device is very comfortable to hold. All mouth areas can be reached properly. The cleaning effect can be clearly observed in the rinsed-out leftovers. I am with this device, even after some 12 months, yet totally satisfied. A battery-Fatigue is absolutely not determine.
