I have had mine for only 10 days. It's so easy to use! I find the power button to be super sensitive, changing even when my finger gets close to it, and I have a little trouble figuring out which Mode I’m in. It's very easy to fill and empty but I wish the User Manual told me whether vinegar is needed/recommended, since so many sites on the internet recommend using a couple of tablespoons of vinegar in the cleaning water.
