After a summer of moderate use, the rotating base broke. It is not justified for its price.

Good in appearance and satisfactory remote control.
Three speeds possible, even the low one.
Aerodynamic noise higher than desired even at low speed.
The blade has 5 narrow wings, which means more turns to do its job, thus more noise.
In sleep mode, inappropriate programming.
It adjusts the speeds every 5'' from quite low to medium, which is unacceptable for sleep.
It needed adjustment at the lower speeds and constantly.
For me, the sleep mode is unacceptable and noisy, so I return it the next day after purchase.

The motherboard had a problem in the first month. I didn't send it back because I got tired of dealing with it. The two speeds were working until it completely froze in the third quarter.

I don't know why it doesn't have good reviews, but this fan works non-stop for me for the third summer. It is sturdy and I believe it has good build quality. Yes, it makes noise like all fans, but it is very powerful. I have it in my 50 square meter living room and its coolness reaches every corner

It is a very nice and powerful fan, no comparison to what I had before. The remote control helps a lot in its operation.

From the first month, no button works. Only with the remote control and I don't know for how much longer.

I have the same model but it doesn't have the remote control. It is relatively good in terms of quality. Many people are right when they write about the stand, it really takes two people to hold this thing. The fan blades are very good in terms of plastic quality, it breaks for fun, that's why I kept something more flexible than another fan that got stuck with the motor, for better or worse. It is very powerful but also very noisy.

From the first month, without working much, it probably burned the circuit board and the buttons do not work, neither from the body nor from the remote control, nor the indicator lights. It moves forward only when I put it in gear by itself and stops only if I take it out at the speed it was left and stationary

Very bad choice. I don't know if I got a defective one, but it broke within a month of mild use. From the first week, it only worked through the remote control (the buttons on the body didn't respond), and as soon as it reached the end of the month, the motor cables overheated, smelled burnt, and it never worked again. I won't even comment on the assembly of the shells with a wannabe rubber that tightens with screws. Maybe the worst purchase I have ever made, I hope at least my money will be refunded.

Low-quality materials. It takes oceans of patience to connect the crown (it doesn't sit with anything and the screw is just for throwing away). It's not worth its money, buy another brand (even the simple fan of a well-known household appliances company connects more easily and is of better quality with much less money).

The functions it has are not practical at all. It has also been mentioned by others that even at the lowest speed, it is quite powerful and noisy. The natural and normal modes are reversed in mine (in nat it is a constant speed and in nor with adjustments). The sleep mode is only good for getting rid of your partner from the bed... not good at all. I only operate it at the first speed, it feels like a second speed for others I had. It is not suitable for sleep, too noisy and powerful. Also, on the second day of use, when I rotate it, it sounds like a tooth jumping at one end.

Unfortunately, even at the lowest level, the fan spins very fast, the air is very strong, and the noise from the blades is loud. I do not recommend it.

One of the worst choices.. It has 3 operating modes, of which 2 are completely useless the way they function, and the 3rd one simply blows normally with moderate noise intensity!

Everything is good, but the sleep function is a bit all over the place. It starts off with little power and is actually quiet, but then it starts revving up like an F 16. You can't have it consistently working calmly. Even in sleep mode, it makes adjustments to give you a sense of natural flow.
*EDIT* Purchased on 1/6/2022.... On 14/6/2022, it made a noise, fell, and both the general function and the sleep function stopped working. It's dead. It doesn't work. It's going in the trash
