Query: 3rd one in 3 weeks

As a humidifier it works well but I'm on my 3rd one in as many weeks. The first one had a malfunction in the LCD screen and the 2nd one constantly shut on and off while it made a horrible growling noise. We'll see how #3 holds up. When its working it performs well but I am having doubts about the quality control. I'm sure it's another quality Chinese product. Amazon has been terrific to deal with.#3 had a defect as well. The indicated room temp stayed at 32 degrees no matter what the actual room temp. I tried blowing warm air over the sensing unit but it stayed at 32. I think I'll live with it because the reviews on the other humidifiers are not very good. At least this one does not leak and performs well.On 5-15 the third one failed. These things are junk.
