I was given it as a gift, but unfortunately it turned out to be much inferior to my expectations. Initially, I put a little water in the compartment and opened the sprayer, which makes a continuous annoying noise like a whistle. Then I discovered that all the water was leaking from underneath, even though the cap was closed. I put the two ice packs with water in the freezer and when they froze after many hours, I put one in the special compartment in the machine, but the difference in the cool air was barely noticeable or nonexistent. Another big drawback is that it does not have scales for the air intensity. Overall, as a machine, you can say it's useless. There are much better options for the same price. I would not recommend it
