Query: Excellent--when it works!

I used this humidifier for a little less than a month when it just stopped working. Amazon was excellent in replacing it immediately; however, the replacement worked for approximately two months. It also just stopped working. Amazon wouldn't replace it a second time and actually sent me an e-mail saying they are experiencing too many problems with this humidifier. Honeywell replaced it for me; I can't say how well the 3rd one works as I haven't used it yet since the winter months are over. I love this humidifier when it works; but unfortunately, that only happens for a very short period of time from my experience. There is some inherent problem with this product; although I asked Honeywell about their experience with returns and what kind of problem it has, I never did get an answer. I would love to recommend this product, but I can't as there is no longevity to it all.
