Negatives:
- It does not have an on-off button.
- It does not have an indication if it is working, you just have to wait and see if it will work, if you have managed to connect the cable properly.
- To fill it with water, it has a safety lock and you have to unplug the power cord and then open the lid. To reconnect the cable, you have to secure the top part very well, which is very difficult.
- You can never completely empty the water, it is designed that way. So you have to let it dry, which makes it very difficult to clean the container.
- It consumes a lot of electricity.
- It is very sensitive if the tap water is not good, resulting in burning a fuse internally or even the resistors.

Positives:
When it works, it does a good job...

I wonder about their design that doesn't even have a light, an on-off button, or at least the ability to empty the water...
