good model, I liked it.
1 February 2016 
I bought it and installed it to cool two zones in one room separated by an incomplete partition. In general, it was originally purchased for the room, but in fact the power and blowing power turned out to be enough to also cool the kitchen with the hallway, that is, in fact, my entire single room. Immediately after the purchase, I thought that the indoor unit was too small and most likely does not pull out those 35 m that the manufacturer guarantees, in the end it turned out that I probably could have done more. The outdoor unit is not immediately behind the indoor one, so a solid estimated length of communications of 15 m turned out to be most welcome. The inside itself is very well designed, a matte surface and a minimum of unnecessary details, as for me, it’s only good, dust will clog less, which means it’s easier to wipe. In terms of functionality, everything is also quite advanced, there is a ventilation mode, I use it when I leave home for a week to circulate air. Starting up after a long idle time does not go right away, but with the self-diagnosis process, of course, you often want this diagnostic or self-cleaning to occur after the device is turned off, but it’s good that the conder itself worries about its condition and that it definitely won’t suddenly fail. By the way, it turned out to be very useful in the end to remember the settings after disconnecting from the outlet, at work the conder does not have such a function and you often have to set everything up from scratch after the loss of light.
Confident work. Convenient remote control with large keys. Clear instructions, which helped a lot since this is the first Conder. European assembly.
The price is clearly not affordable. The remote control does not have a backlight, although I saw this option even on cheaper models.
If you want to save money, this isn't the best option. But it's the best conditioner!!!

Great air conditioner! Absolutely amazing. I'm writing this review in an office with a Tosot (which is a pretty decent device), so I have a basis for comparison. Let's start with the remote: for the first time, I see a remote on high-end technology without unnecessary buttons. I can't say I use all of them, but the purpose of each one is singular and clear (unlike the Chinese one, where half the buttons are useless and not even always understandable after reading the manual). I agree that Daikin messed up with the backlight. At their price level, an extra 5-10 bucks for built-in backlighting wouldn't have made any difference.

The indoor unit itself is stylish, but for 2018, it's a bit large in dimension. However, the color of the plastic is very nice, matte white... but not snow-white. The installer covered the conduit with a snow-white plastic cover, and it noticeably differs in color. For perfectionists like me, this can be a blow.

There are plenty of modes, but I use the automatic mode in comfort mode. It's very efficient and extremely quiet. However, if you turn off "COMFORT" and set the fan to "SLEEP," the air conditioner becomes inaudible. That is, it cools just as well, but you can't hear it at all... AT ALL! Fantastic. No Chinese model offers this effect even remotely. It feels like the air conditioner is off! The Powerful mode is great for quick cooling/heating, but I don't quite understand who uses ECONO (this is a power limitation mode if the air conditioner is plugged into the same socket as a vacuum cleaner, oven, and jackhammer). The idea of timers is implemented perfectly and is very useful with smart use!
device functionality, quiet operation (especially sleep mode), smart remote with excellent interface, 36 months warranty, stylish plastic and exterior design of the indoor unit.
ultimately - nothing. It would be great to have a backlight built into the remote control and the option to disable temperature identification on the indoor unit (in this sense, the Chinese are cooler). Many people consider the price a drawback... well, then I know the main drawback of a Mercedes. When you fall asleep with the Daikin on, you surely understand what you paid for.

functional model from a proven brand
28 January 2016 
I bought this one for my living room, which is 20 square meters, so I chose an air conditioner with a bit of reserve to cool up to 25. During the selection stage, I immediately dismissed all options with the Chinese brands that claim to have "everything like the expensive brands", but somehow they are twice as cheap. After all, an air conditioner is not some kind of kettle and it's purchased for several years. Visually, both the indoor and outdoor units are pleasing, although to me, the indoor part looks somewhat overly simplistic. The remote has large buttons, and since there aren't many of them and they are well-spaced, I began to press them without looking over time. When I was selecting a suitable model, I read in reviews that many people complain about the lack of backlighting on the display, saying it's inconvenient to use at night; I don't use it at night, and during the day, all the indicators are clearly visible and understandable. Another important feature for me in this model is its operation down to -15 degrees. There's a heating function; I'm not saying I heat the house with it in winter, but the fact that during periods of slush and down to -8 it effectively removes excess moisture from the room is just excellent. You can set a timer on the remote, and the air conditioner will turn on according to a schedule.
- a well-known and trusted brand;
- the package includes fine air filters, so you don't have to buy them yourself initially;
- the white matte plastic of the indoor unit looks expensive and solid;
- easy-to-use and convenient remote control;
- quiet operation even in intensive mode, at work there's an Ergo, which sounds like a tractor compared to Daikin.
- would like a more interesting design for the interior;
- the remote beeps excessively loudly, sometimes I feel like prying the speaker out of it.
