I love the way it looks and sounds but not the instructions.  Very vague. I notice it quit working about 2 weeks of running when I went to turn it off before going to bed.  I thought maybe it was low on water.  I put more in and still didn't start. Trouble shooting hints didn't cover this.  I was going to call in the morning for help but in the morning I tried it and started working again.  Hopefully it won't happen again.  I'll probably be calling to ask if it's suppose to continually run or should it be turned off at night, like I have been doing.  This is not cover in the instructions.
