Yangzi Dehumidifier day 3 update

Yesterday I wrote about the Yangzi Dehumidifier CS-10E unboxing
Now I've hade it running for about three days. I turn it on when I wake up and off when I go to bed
Water collection
About 100-120ml is collected each day of testing. Most is collected the first few hours of turning it onIt does collect water from the air, there's no doubt about that part. I was cooking earlier and it got pretty steamy. That's around when I felt most got collected and is an area I want to do further testing in
Humidity
Humidity while it's been running, have felt slight lowerWhen looking at the humidity sensor on the device and the ones I have around my house. It has gone slight down
Today it's also been slight colder outside (about 2°C less), compared to the previous days. Which of course also impact on how humidt it feels
If it helps enought to justify the purchase of a device like this and the cost of operating it, I'm not yet sure
