It's a shame that the height adjustment and angle cannot be adjusted downwards, but overall I'm satisfied.

I was going to return it because of the noise, but the cost performance is so good that I'm just sick of it. The seller's response is really fast and I like it.

At the time of purchase, I bought it without knowing it was this kind of product. First of all, there is no indication on the machine, at least there is not even a small light. You never know if it's working. The noise smells great ㅜㅜ And what's the difference? go by go? There is a sound, but I'm anxious. The important thing is that the third level is cold air, warm air, and strong warm air. Only cold air and warm air come out.
