Some measurements for its efficiency in a room with 19°C / ~60-65% humidity.

On continuous mode, alternating 2 half-hours on low speed and 2 half-hours on high speed:
1st 30 minutes (high fan speed): ~210ml - consumption around 215w/hr.
2nd 30 minutes (low fan speed): ~185ml - consumption around 225w/hr.
3rd 30 minutes (high fan speed): ~220ml - consumption around 215w/hr.
4th 30 minutes (low fan speed): ~170ml - consumption around 225w/hr.

Immediately after, half an hour on DRY - 175ml - consumption around 750w/hr.

Conclusion: It performs better on high fan speed, producing around 2lt / kwh which is very good for the times we live in, where every kwh counts.

On the negative side, the plastics smell (it is new). We'll see when the smell goes away. The sound at fan speed 2 is not silent but it is not particularly annoying. On 1 it is much more civilized but efficiency drops by about 15-20%.

Update after 6 months: It continues to perform very well but the smell never went away... it always needs about 10-20 minutes with the window open to air out the stench before I put it in the room. Also, a resonance/rattle appeared with the compressor and some plastic, which is resolved if I place a weight of about 3-4kg on the top plastics.

Update after 2 years: It continues to perform at around 400ml/hour, finally the smell is gone. The rattle/resonance disappeared on its own (?).

Beast.
From noise, it can be heard on level 2, on level 1 it's okay.
The only thing is that recently, it has done the following 3 times (that I noticed):
While I closed it, after some time (around 10 to 30 minutes), it opened by itself again!
If it continues, I will talk to the inventor and I will come back.

Update 1/7/22: I have the impression, after observation, that if you set the timer on the dehumidifier, for example, to work for 3 hours and you go and turn it off earlier, it does this strange thing where it turns on by itself again after a while. I will check it again in the autumn.

The machine is a beast, I have no words.
In automatic mode, it consumes about 220 watts.
Be very careful, in smart mode for clothes, it increases consumption vertically, about 750 to 800 watts.
I hang the clothes in a room, set it to automatic at 40% and they dry perfectly and economically.
I think the noise is fine, considering its volume and power.

4/2024 and it remains a beast. It collects ALL the water.
Performance remains the same. I regularly clean the filter. I also opened the back cover and did a biological cleaning myself on the element.
It was a bit dirty, I expected a much worse condition. I am very satisfied with the machine.
Also, in continuation of the above observation, when you set the timer and go and turn off the machine from off, after a while it opens and works.
This has only happened to me when I have set the timer.

After 4 days of operation and collecting 12 liters of water in a house with very good thermal insulation and new aluminum windows—basically a new house on an island with very good heating from an energy fireplace and radiators running daily—I did not expect it to collect so much water and to keep the humidity from 80% down to 40%. The noise is very normal on the first setting for such a powerful machine; you can sleep normally if you have it in a hallway next to the room. On the second and more powerful setting, it sounds like an air conditioner. I want to emphasize that in smart mode, the air that comes out is warm, which is why the manufacturer recommends it for winter. Very satisfied and I highly recommend it. If you are picky about noise in general, no dehumidifier will satisfy you except Mitsubishi, but that costs 500 euros and is not for large spaces.

After two years, I have to say that the machine is a tool; it brings the humidity down to below 30% on an island in no time at all…

After 6 years, I have to say it's the best on the market; unfortunately, its production has stopped.

If you find it somewhere, somehow, get it yesterday.
