8/7/2020: In the month that I have it, I found that it is very efficient in cooling (I will return in winter) and completely silent (18db in quiet mode) air conditioner essentially in noise with the Tundra Green I have...
Add the 5-year warranty without maintenance obligation and other terms with the name inventor guaranteeing it and you are ok!
Update: maintenance is required from the 3rd year onwards.
It goes down to 280 watts minimum consumption in cooling.
Super civilized operation inside-out.

9/11/2020: First cold, therefore, 9 Nov 2020, with 11 degrees outside it goes down to 340w. Operating cost 6 cents per hour with a price of 0.15737 kwh on 9/11/2020 (with taxes, etc.).
Very satisfied also in heating.

7/2022 and remains very decent.
I have yet to add that it is essentially the same as the newer one called Tide Green Plus as well as with Pearl, except of course for some additional technical characteristics, such as WiFi in Plus and UV sterilization even in Pearl.
You should know that it has a rare feature for a bedroom, its blinds turn and hit the floor completely vertically.
So it doesn't matter even if it's next to the bed...

New Update... I dared and put in August 2022, in my living room, in the same space as the Haier, a Daikin Siesta Sensira 12, from the series, the cheapest model, with 550e then, now 580e.
The results in all fields were overwhelmingly in favor of Daikin even though their characteristics are almost the same (despite the fact that Daikin is 12 and Haier is 9), in the specifications.
I will highlight, for example, the 40% reduction in consumption in cooling, after successive measurements that I couldn't believe and finally after the winter that confirmed it there with an even greater difference, I even exclaimed hallelujah!
Otherwise, I realized that at least Daikin and Toshiba (as I bought for the northern bedroom also a cheaper 9 of the series) have a good programming of air conditioners that makes everything run smoothly and steadily and economically with highly refined and civilized behavior and operation.
I have now eliminated the pellet stove and work 24/7 because it is more economical and with less money than ever before (except for the coolness) and abundant warmth.
Finally, I added to the same space just in case the Sensira 12 is not enough and out of curiosity a Daikin Perfera 9.
Again 40% difference, from Sensira 12, however, which surprised me because although it is a category above Sensira, but so much??? And yet if we assume that the Haier "burns" 100kwh per month, the Sensira burns 60kwh and the Perfera 36kwh!!! It's a pity that due to the "recycling" programs, traders have reached the Perfera 9 today in July 2024 at over 1000 euros and the Sensira about 100 euros cheaper.
Honestly, by buying one of these two Daikin or Toshiba, you will make a gift to your home that will last long term (Toshiba: 7-year warranty with the only condition of annual maintenance and moreover if you prefer its network it is at 20-30 euros at most) (Daikin 3 years + 2 free for purchase from its network, extension to 10 years with about 100 euros with the only condition of annual maintenance and moreover as in Toshiba, if you prefer its network it is at 20-30 euros at most).
I will change the track with these two companies from now on... with today's electricity prices, we can't joke around with purchases that maybe wouldn't bother us in the past, but now?
Imagine, the Haier lost its freon and I don't even feel like refilling it... maybe only if I uninstall it and put it in a space that doesn't require much and I have an old on-off.
