Product review (1 stars): What a disappointment.....
I have had no issue getting this item to work and continue working.  But after a day of use, I dumped a bunch of nasty water out of the top portion.  I am not sure if that makes this humidifier something that is healthy to use.  Aside from that, I love this.  I have purchased other cheap humidifiers with poorly written english instructions and this is the best one of that grouping.  Scratch all of that, in the time it has taken me to write this review, the blue light turned off and the humidifier stopped working.  I have only had it a few weeks.  Not happy.

UPDATE!
I am returning the humidifier as the water must have gotten into the housing for the electrical stuff.  It was all brown and gross on the inside.  I am very disappointed as this worked amazing for me while it lasted.  I wish that this product still worked as I think I was about to put out the first good review on it, but like everyone else before me, this item just did not cut it for me.  I have been using it for only 2.5 weeks.  This is not ok.
