Better than all ultrasound equipment

Then it spent more money and bought the unit from Wick - wow, what a difference.

Operation OK, cleanability of the parts that contact water well, function very well.

Three disadvantages are not to conceal, but not decisive for me:
- Because of the functional principle of higher power consumption than an ultrasonic device
- Greater sound than the one ultrasound device (I could not sleep next to my son sleeping problems here)
- The cleaning of the water tank is, as with all appliances, not reasonably possible, because the only opening is too small to get in by hand (everything else that comes in contact with water, can be very easy to clean).

Conclusion:
I would buy again immediately and would highly recommend.
